Frequently Asked Questions

Is my colour data sent to a server?
No. All colour operations happen entirely in your browser using JavaScript. Nothing is transmitted.
What colour formats are supported?
We support HEX (#RRGGBB), RGB (0–255 per channel) and HSL (degrees, %, %). Results copy directly into CSS or any design tool.
What contrast ratio passes WCAG?
WCAG 2.1 Level AA requires 4.5:1 for normal text and 3:1 for large text (18pt or 14pt bold).
Can I use gradients directly in CSS?
Yes. The gradient generator outputs a ready-to-paste CSS linear-gradient() declaration.
How many colours does the palette generator produce?
It produces a 5-colour tonal range from your base colour. Apply the tool with different hues to build a larger palette.
