Yeah the goal was simply to find the closest paints for specific RGB values from a reference image for a pointillism project I was working on.
I wasn’t trying to do the impossible and find the absolute perfect real-world color match. Just something close given the limited palette of acrylic paint brands I could find locally.
I pulled out the RGB values from the solid color areas of the swatch images on the manufacturers' websites for each of the colors.
It's definitely just an approximation of the real-world color, but I figured that if that's the RGB value the manufacturer used, it's probably pretty close.
Then I calculate the euclidean distance between the RGB value from the provided hex and each of the paints, and show the two closest matches from each brand.
Any specific artist brands you'd want to see added?
