Title: Color Theory Lab Prompt: A hands-on Bauhaus color printer for mixing harmonies, inks, and contrast. Combine a hue wheel, RGB sliders, harmony strips, a two-ink mixer, and an accessibility checker. It should feel tactile and print-like — hard shadows and ink borders on warm paper. Design: A paper lab with thick ink borders and offset hard shadows splits into base-color mixing, a central harmony and blend stage, and a contrast plus library rail. The canvas wheel picks hue, swatches pin to the library, wells blend into a gradient bar, and the AA box flips foreground and background live. Visual techniques: - Canvas hue wheel with printable ink ring and spin animation - Harmony strip tiles with stamp-in keyframes - Two-ink wells blending into a live gradient bar - Hard-shadow neo-print buttons with press states - Warm paper palette with red, yellow, and blue primaries Interaction model: Users pick hues on the wheel or via RGB sliders and swatches, switch complement, analogous, triad, and tetrad modes, pin swatches, mix two inks with a blend slider, flip and test contrast ratios, copy hex codes, and read rotating color lessons.
