Frequently Asked Questions
How do mood filters mathematically constrain randomness?+
Rather than drawing purely unconstrained random integers across 0-255, mood filters constrain the HSL cylinder: Pastel restricts Saturation to 50-70% and Lightness to 80-92%; Dark restricts Lightness to 10-30%; Warm constrains Hue to 0°-75° and 330°-360°.
Can I use keyboard shortcuts to generate new colors?+
Yes. Simply press the Spacebar anywhere on the generator canvas to instantly trigger a fresh random re-roll.
