海外TECH	DEV Community	Using Virtual Color Mixing to Extend Your Palette in React/JavaScript	https://dev.to/bytebodger/using-virtual-color-mixing-to-extend-your-palette-in-reactjavascript-l41	Using Virtual Color Mixing to Extend Your Palette in React 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 last article I illustrated how we can mix paints virtually We can take two colors and mix them together to see what the resulting paint will look like Although this can be useful in theory e g to determine what two paints will look like if we mix them together in the real world this also has practical applications for the live app that I ve built at The limitations of color depthIn the previous articles I showed how to pixelate an image so we re not dealing with millions of colors I then showed how to find the closest match between a given color and a reference palette of colors Finally I showed how to use dithering to ensure that those closest matches were not all bunched together in specific bands of colors For reference this was the original image that we d pixelated using a basic RGB algorithm This image isn t bad We don t have any annoying color bands because we ve employed dithering And the colors on the transformed image are acceptable Granted there are a lot of pinks reds on her face a fact that seems a bit odd considering that she s a woman of color And overall you could argue that the image is a bit noisy But if you step back and blur your eyes a bit the coloring on her face doesn t look entirely unnatural But I m not entirely satisfied with this image As previously mentioned there s a lot of red pink in her face where maybe it shouldn t be Given that I started with an original palette of paints why is it that the transformed image has many colors that still don t seem to properly map to the source image The answer lies in color depth Paints are inherently darkThere s a reason why it s inherently difficult to perform color matching when your source image contains a subject like a human face but your reference palette consists of stock paints The reason is that Paints especially professional grade paints are fairly dark in nature For example Even though I have paints in my inventory here is the color key for all of those paints If you look carefully at that selection you ll see that we have all of the normal colors one would expect to find in a palette of paints There s black and white and numerous shades of grey But there s also reds and oranges and yellows and greens and blues and purples and browns So why does our algorithm still fall short when trying to match the digital image to those paints Well for starters take a look at that palette Although we have a broad spectrum of colors nearly all of those colors are exceedingly dark FWIW this is by design You see when you buy professional grade paints those paints come with a very high pigment load The idea is that you can mix them with other paints and they won t immediately lose their core qualities because the original paints are chock full of pigment But what this means in a practical sense is that all of the off the shelf colors are really quite dark And of course some images are chock full of dark colors So if you match those images against our palette of heavy body acrylic paints you may find that the color matching performs quite well But with something as nuanced as a human face Well it causes problems For example this was the original image we were working from Clearly this is a Black woman But just as white people are not truly white they re mostly a mix of yellow pinks tans most Black people aren t truly black they re mostly a mix of browns yellows tans Furthermore the skin tone of most Black people isn t really all that dark They re dark compared to white people But in the image above you can see that many areas of her face are actually quite light When you add in additional factors such as lighting and makeup their skin can in certain regions be incredibly light So although we have a fairly workable transformation of the image matching the pixels in her face to the colors in our paint inventory there are still areas where this transformation falls short The answer is to extend our palette of colors Making darker colors lighterIf we wanted to we could use the color mixing algorithms from the previous article to create a whole list of new colors based upon mixing all of the original colors together in different proportions But remember as I stated above our core palette of paints already gives us a pretty solid representation of every base color that we d expect to find in an image The problem isn t that we re missing any base colors The problem is that all of those colors are simply too dark But how do we find those lighter colors If you read the first article in this series you know that I found all of the RGB equivalents for every paint in my inventory by physically squeezing some of the paint onto sheets of paper Then I photographed those sheets and grabbed the best possible RGB value that I could find from every blob If we wanted to find the lighter equivalents of our base colors I could repeat that entire process I could mix in the real world bits of white paint with the original paints Then I could set the mixed bits out on paper wait for them to dry photograph them all and then grab the appropriate RGB values from each lightened blob But that would be quite frankly a real pain the backside Based on the previous article we already know how to mix paints virtually So there s no need to create a massive set of test paint swatches and then manually grab all the RGB images from those swatches Instead we can mix the core colors with white virtually and then use the virtually mixed values to enhance our color matching Using code to find lighter colorsSince we already have all of the core colors in our base inventory of paints and since those colors are inherently dark we can find many more variants of those colors by merely adding white to them In different proportions Specifically in my Paint Map Studio app I ve created five additional color palettes on top of the original palette that represents all of the base heavy body acrylic paints Those additional palettes are as follows WhitesThis consists of parts of every heavy body acrylic paint mixed with part of white This is what they look like WhitesThese consist of parts of every heavy body acrylic paint mixed with part of white This is what they look like WhitesThese consist of part of every heavy body acrylic paint mixed with part of white This is what they look like WhitesThese consists of part of every heavy body acrylic paint mixed with parts of white This is what they look like WhitesThese consist of part of every heavy body acrylic paint mixed with parts of white This is what they look like The beautiful part of all this is that to create all of these other potential colors I didn t have to actually mix any paints at all I merely allowed the algorithm to tell me what these colors would look like if I were to mix the paints in these proportions Obviously you could continue to expand these virtual palettes ad infinitum You could create a Whites palette that consists of part of every heavy body acrylic paint mixed with parts of white But at a certain point you re just creating an ever increasing number of virtual paints that have little distinction from the other palettes Also if you somehow found yourself with an incredibly pale set of reference colors you could then create a series of virtual palettes based on what would happen if you mixed them with varying degrees of black But since our base palette is already so dark this approach has little value in Paint Map Studio Visualizing additional palettesSo what effect does it have on our transformed image if we use a deeper set of colors Well let s remember that this was our originally transformed image This results from performing color matching against only the base set of heavy body acrylic paints Now this is the same transformation except that we re matching against the base set of heavy body acrylic paints and the set of Whites Notice that merely by adding one more set of colors we ve already reduced the noise in the image by a great deal and we ve eliminated most of those jarring red dots on her face Here s the same transformation with Whites also added to the mix The improvement isn t nearly so dramatic But it s still smoother than the previous image Here s the same transformation with Whites also added to the mix Honestly at this point we re already reaching a degree of color depth where it s hard to see the difference between this image and the previous one But let s keep going at least for the sake of illustration Here s the same transformation with Whites also added to the mix And finally here s the same transformation with Whites also added to the mix Now that we ve added all of these extra palettes our color matched fully transformed image looks incredibly similar to the original By adding many different lighter shades of our original base paints we ve managed to create a transformed image that s incredibly true to the original And we ve done this without creating a whole series of funky custom color mixes Every block in the pixelated image is represented either by one of our base paints or a variation of those base paints that only entails mixing it with varying degrees of white I find this to be incredibly useful because I really don t want to bother with a painting where this block requires parts of Golden Cerulean Blue Deep part of Liquitex Green Gold and parts of Liquitex Cadmium Yellow Light but the next block requires part of Golden Cobalt Turquoise parts of Golden Burnt Sienna and part of Liquitex Deep Magenta It s far easier to know that every block in the transformed image either maps to an original paint color or some proportion of that original color mixed simply with white In the next installment We re coming close to concluding this series but we re not done yet In the next installment I ll show you how to restrict the resulting color depth so that you re not faced with having to mix hundreds of paints to produce a given image	2023-02-28
