海外TECH DEV Community Color Mixing With JavaScript https://dev.to/bytebodger/color-mixing-with-javascript-1llh Color Mixing With JavaScript NOTE The live web app that encompasses this functionality can be found here All of the underlying code for that site can be found here In the previous articles in this series I talked about many aspects of color theory and real world paints as they apply to web development i e RGB colors Soon I m going to show you how to apply algorithmically created palettes to a digital image But first we need to cover a basic task Virtually mixing paints with code Honestly there are a bunch of sites out there that can already do this for you But I didn t see too many that actually talk about how you do it So I m going to illustrate that here RGB mixingObviously the RGB color space is comprised of numbers Three numbers to be exact representing red green and blue So if you wanted to mix two or more RGB colors the mathematical way to do that is to simply average the reds and the greens and the blues The resulting average will yield the new mixed color I ve already determined the RGB equivalents for each paint in my inventory For example Golden Light Magenta is const goldenLightMagenta red green blue And Golden Cobalt Blue is const goldenCobaltBlue red green blue So if we mix those two together the resulting color would be const newColor red Math round green Math round blue Math round Which comes out to const newColor red green blue CMYK mixingCMYK also consists of numbers But it has four numbers cyan magenta yellow and key instead of red green blue The color mixing I ve implemented on Paint Map Studio uses CMYK mixing Why Because CMYK is a subtractive color space and using CMYK values tends to lead to mixing results that are slightly better in my experience For example when I mix Golden Cobalt Blue with Golden Light Magenta it gives me the following result const newColor red green blue And the mixRgbColorsSubtractively function looks like this const mixRgbColorsSubtractively rgbColors rgbModel gt let cmykColors rgbColors map rgbColor gt convertRgbToCmyk rgbColor let cyan let magenta let yellow let key cmykColors forEach cmykColor gt cyan cmykColor cyan magenta cmykColor magenta yellow cmykColor yellow key cmykColor key const cmykColor cyan Math round cyan cmykColors length magenta Math round magenta cmykColors length yellow Math round yellow cmykColors length key Math round key cmykColors length return convertCmykToRgb cmykColor Since I m building all of this in a web based application I m always starting from an RGB color That s why the function expects an array of RGB values Inside the function we convert the values to CMYK calculate the average and then convert that average back into RGB You can see this logic in action by going to On that page you ll be able to pick any colors from the palette of heavy body acrylic paints mix them together in different proportions and see the resulting color It may surprise you to see that the RGB model yields a color mix that s so visually similar to the CMYK model Well let s explain that Beware of color confusion In my experience it s really easy to get your head wrapped up in knots when thinking about color mixing I think this confusion comes about because of the way that we talk about color mixing and color models For example I found this quote on a site that talks about RGB vs CMYK colors The color systems used by scientists and artists are entirely different An artist will mix blue and yellow paint to get a shade of green a scientist will mix green and red light to create yellow To be perfectly clear this quote isn t wrong But it definitely has the potential to screw up our thinking because it s talking about two different types of mixing Specifically there s a difference between mixing and combining Let me show you According to that quote a scientist would mix green and red light to create yellow But that s a bit misleading because the term mixing implies that I have two RGB colors one green and one red and we re mixing them up So using the basic calculation that we outlined above for RGB colors that means that we would be mixing these two colors const green red green blue const red red green blue What happens when we mix those up We get this const mixedColor red green red red red green green green red green blue green blue red blue Which comes out to this values rounded const mixedColor red green blue And that RGB value looks like this That s hardly what most people would call yellow Sure it s kinda sorta yellow ish But it s far from true yellow I think it would best be identified as a dirty chartreuse Here s where the quote isn t entirely wrong but it s definitely somewhat confusing In the RGB color space combining pure red and pure green in a single color will indeed create yellow In other words this value const fullRedAndFullGreen red green blue Creates this color Now that is yellow But it only happens when we combine red and green into a single color It s not what happens when you mix red and green together Here s another way to think about it Imagine that the scientists mentioned above has a laser on his desk that emits wavelengths of pure red light And he has another laser that emits wavelengths of pure green light Using the RGB color space we could represent his lasers as such const greenLaser red null green blue null const redLaser red green null blue null Notice that for the red laser I didn t define the green and blue values as I defined them as null And on the green laser I defined the red and blue values as null If you understand the difference between and null and if you re reading programming blogs I sure as hell hope that you understand the difference you ll realize that an RGB object with null values is not the same as one with values Now if that scientist were to combine the light coming from the red and green lasers the resulting color would indeed be yellow But if that same scientist was creating a web site to present his findings and he wanted to mix the RGB color red with the RGB color green the resulting color would be chartreuse Not yellow The exact same thing happens if we use a color space that s subtractive like CMYK rather than one that s additive like RGB The CMYK Venn diagram tells us that combining pure yellow with pure magenta should give us red But let s look at what happens if we don t combine them but instead we mix them Our colors would look like this const yellow cyan magenta yellow key const magenta cyan magenta yellow key Mixing them is accomplished like this const newColor cyan yellow cyan magenta cyan magenta yellow magenta magenta magenta yellow yellow yellow magenta yellow key yellow key magenta key Which would come out like this const newColor cyan magenta yellow key And the here s the resulting color That s umm red ish But it s far from pure red It s much more like a salmon color In fact it s incredibly similar to the Golden Light Magenta color illustrated near the top of this article This is why IMHO color mixing can sometimes lead people down rabbit holes They spin up a color mixing algorithm that uses CMYK for example then they throw pure yellow and pure magenta into the mix and when the resulting color isn t pure red they think that there s some kinda flaw in their methodology I ve read many threads that complain about this exact same problem on places like Stack Overflow But if you have a pure yellow colored paint and you mix it with a pure magenta colored paint I promise you that you will not end up with pure red You ll end up with salmon In the next installment Although this topic interests me from the perspective of further understanding color theory I didn t take you down this path purely for academic reasons Being able to accurately mix paints algorithmically will have significant benefits in our quest to create a palette of near perfectly matched paint colors against a digital image In the next article I ll show how we can leverage this to greatly increase the accuracy of our transformed images That being said even if you re not interested in trying to match a digital image to a given palette of paints it can be extremely useful to be able to mix paints virtually I m sure that skilled artists already have a good feel for the colors that result when they mix any two or more paints from their inventory But for the rest of us it s nice to be able to see the results without having to create an endless stream of paint swatches 2023-02-28 06:35:32
海外TECH Engadget Xiaomi's 300W demo fully charges a phone in five minutes https://www.engadget.com/xiaomi-300w-charging-five-minutes-062341344.html?src=rss Xiaomi x s W demo fully charges a phone in five minutesBack in late October we saw Xiaomi releasing its W mobile charging tech by way of its Redmi sub brand and this was eventually beaten by a W version from Realme ーpart of the Oppo and OnePlus family ーin early February Given that it s MWC week today Xiaomi swiftly responded with a whopping W demo which brought the charging time down to a little under five minutes ーalmost half that of the two aforementioned achievements Xiaomi added that this new W charger comes in the same size as its earlier W counterpart thanks to a better modular design plus heat dissipation on the inside The W demo featured a Redmi Note Pro modified with a mAh battery which is a little smaller than the mAh in the W Redmi Note Discovery Edition and the Realme has a far more generous mAh As you can see in the video the phone reached percent in just a little over one minute followed by the percent mark in minutes seconds and then percent in just a little under minutes The power meter indicated a peak input of a little over W for the charger and it also managed to sustain W and above for around two minutes at one point The company said the battery here pack more powerful C cells as opposed to the C cells in the Discovery Edition which consist of new carbon materials in place of some of the conventional graphite parts thus reducing the electrodes thickness by percent Together with an improved electrolyte formula this lithium ion battery can pack a higher power density with a faster charge and discharge rate while apparently reducing the amount of heat produced in the process These ultra thin cells are then stacked with thermal materials in between as part of a new quot sandwich quot design in order to optimize heat dissipation while making better use of internal space As far as safety is concerned Xiaomi claimed that there are over features built into the system to keep tabs on the current voltage and temperature on each charging chip Xiaomi s announcement today has definitely set another milestone for the mobile industry though the company didn t mention whether this W charging tech will be mass produced Nor did Xiaomi share figures on charging cycles which makes for a sober reminder of how battery lifespan can be affected by higher charging power 2023-02-28 06:23:41
