Can I use this with the main generator?
Yes. Start from this page, then open the main Chromoforge tool with the same base color and export the palette.
How many series colors can a chart carry?
Six to eight categorical colors is the practical ceiling. Beyond that, adjacent hues stop being distinguishable at small sizes. Group the long tail into an "other" bucket, or switch to a sequential or diverging scale built from one hue.
Do chart colors need to pass WCAG contrast?
Yes, in part. WCAG 1.4.11 asks for 3:1 between meaningful graphical elements and their background or adjacent colors. Text labels inside a chart still need 4.5:1. Never encode meaning through hue alone: add direct labels, shapes or patterns.
