About this tool
Bright child-friendly palettes with a contrast-repaired text tone for every hue, so overlays and captions still clear WCAG AA or AAA.
The Kids Playful Palette Generator produces bright themed colour sets and then repairs each hue into a text-safe version by walking its lightness one percent at a time until it meets the WCAG 2.x contrast ratio you pick — 4.5:1 for AA or 7:1 for AAA. You get a fill colour for blocks, badges and illustrations, plus a darker or lighter sibling of the same hue that is safe for captions and body copy on the page ground. It suits anyone designing school worksheets, children's apps, nursery branding or family event pages where the colour has to stay cheerful without making words hard to read.

Fills stay saturated for illustration while a separate repaired tone carries the type, instead of dulling the whole palette.
For each fill the tool scores ink, page, black and white and reports the winner with its exact ratio.
Theme, mode, hue rotation and variation fully determine the result — the same settings always give the same hex codes.
Because contrast depends on relative luminance, not on how vivid a colour looks. A saturated yellow has a luminance close to white, so on a white or off-white page it lands near 1.5:1 — far under the 4.5:1 WCAG asks for body text. Darkening the same hue to roughly 28% lightness brings it past 4.5:1 while keeping it recognisably yellow.
WCAG 2.x sets 4.5:1 for normal body text and 3:1 for large text (24px regular or 18.66px bold) and for interface components. AAA raises body text to 7:1. Early readers and printed worksheets benefit from aiming at the 7:1 target, since paper, cheap ink and classroom lighting all reduce effective contrast.
Usually not on a light page. Each colour here is reported with its raw ratio against the ground, and most vivid fills land between 1.5:1 and 3.8:1 — fine for a block of colour or an illustration, not for words. Use the text-safe sibling the tool generates for anything readers actually have to read.
No. Contrast is one success criterion among many. Font size and weight, line length, spacing, focus states, motion and colour-only meaning all matter too, and children's products often need larger type than the minimum. Treat this as a colour check, and test the finished layout with real users.
