Hey guys I figured out something new about color theory in additive color mixing. So, the primary colors in additive color mixing are R, G, and B (Red, Green, and Blue). The secondary colors are C, M, Y (Cyan, Magenta, Yellow). Using basic knowledge we know that R + G = Y R + B = M G + B = C The secondary colors can also be added to make up primary colors: M + Y = R C + Y = G M + C = B We know that from looking at Adobe Photoshop's color wheel that these are the opposite colors: B = -Y G = -M R = -C In further detail: B = -(R + G) = - Y G = -(R + B) = - M R = -(G + B) = - C So essentially Blue is the inversion of Red and Green. Green is the inversion of Red and Blue. And Red is the inversion of Green and Blue combined. This can be further proved in the following: R + G = Y R + B = M M + Y = R M + Y + B = M B = - Y This is all I have in terms of simple equations on color. The rest is analytical. This is the graph of luminosity of different colors. We notice G is the brightest of primary colors, R is the second brightest, and B is the least bright primary color. We notice there is a bump in brightness at C, M, and Y, which are formed by combining two primary colors. This probably is because combining two colors triggers two cones in the human eye that causes the luminosity to shoot up and make the bump on the graph. I believe there is a way to define color as the change in luminosity (slope) and the overall luminosity. I know I am missing a lot of things in this, so can anyone who's knowledgeable about light and physics help me make equations that can define color scientifically and mathematically? Many thanks in advance.
