Adjust the red, green, and blue sliders to the color of your choice, and the project will tell you how "different" the colors are. I am pretty sure there is no limit for how high the color difference is, but it's hard to get far over 100. The easiest way to calculate color difference is to use the Euclidean distance formula with the Red, Green, and Blue components of a color. However, that doesn't give very accurate results. Alternatively, you could weight the RGB colors based on how much each component affects how we see it, or just use HSV. Neither of these still work very well, so people developed the L*a*b* (CIELAB) colorspace, which was designed so the numerical change in the values is the same as the visual change. The CIE also created a color difference formula using it called CIEDE2000, or ΔE₀₀. It is the most accurate color difference formula, and is used in this project.
