## Theory, aesthetics & inspiration

On a screen, color is light, not pigment: red, green, and blue channels add together, each ranging 0–255 and often written compactly in hexadecimal. Mixing light is additive — full red plus full green yields yellow — the reverse of mixing paint. Beyond mechanics lies perception: Josef Albers showed in Interaction of Color that a hue's appearance depends entirely on its neighbors, while Johannes Itten codified contrasts of warm against cool, light against dark. Albert Munsell's system separates color into hue, value, and chroma, giving an emerging image-maker a vocabulary to control mood deliberately rather than stumble into it. Color is relationship before it is wavelength.
