Jazz Warrior, in Your Own Colours

How it works

• Four inputs, one look for every tune. Page, cards, accent and text are yours; the hover accent, the secondary and muted text and the borders are computed from them, so a form’s bars and a seat’s voicings come out in the same colours.
• Checked on every change. The builder reports four contrast ratios as you move a swatch (text on page, text on cards, button text, secondary text) and marks the ones below 4.5:1, so a chord symbol never disappears into its bar.
• Stored locally. Saving keeps the palette in this browser and switches to the custom theme. Pick a built-in theme from the header menu to leave it.
