Frequently Asked Questions
How are the random colors harmonized?
Instead of generating random numbers across the entire RGB color spectrum (which often yields muddy, clashing hues), SimplyUtils generates seeds using HSL (Hue, Saturation, Lightness). It locks saturation and lightness within aesthetic bands and shifts the hue angle by the Golden Ratio (approx. 137.5 degrees) to produce highly cohesive, eye-pleasing palettes.
What does the WCAG AA/AAA scoring represent?
It calculates the contrast ratio between the generated color block and standard black or white text using the Web Content Accessibility Guidelines (WCAG 2.1) formula. A rating of **AA** means the contrast ratio is at least 4.5:1, and **AAA** means it is at least 7:1, assuring your text is readable for users with visual impairments.
Can I lock specific colors in the palette?
Yes! Hovering over any color card reveals a lock icon. Clicking it locks that specific slot, preserving the color while you continue to randomize the surrounding cards using the Spacebar.
Does this generator support exporting as CSS Variables?
Yes, absolutely. The export utility formats the entire 5-color scheme into standard CSS variable syntax (e.g. --primary: #...;) which you can paste straight into your project's global stylesheet.
