Theme Builder

How it works

• Four swatches, one band. You set the page ground, the card colour, the accent and the text. The builder works out the rest from those four, a lighter accent for hover, softer secondary text and a border tone, so every break, kickoff and jam chart on the site wears the same choice.
• Readable before you commit. Four pairings are measured as you drag: text on the page, text on cards, the label on a button, and secondary text. Each shows its ratio against the 4.5:1 floor, so a palette that buries the chord names shows up before you save it.
• Kept on this machine. “Apply & save” stores the palette in this browser and switches the site to its custom theme. The settings menu in the header takes you back to a built-in theme whenever you like.
