The color settings in WordPress control all the color options available in the block editor sidebar, giving you complete control over your block theme’s color system.
Text color controls the foreground color with options for custom color picker, theme palette colors, and WordPress default colors. Background works similarly, offering solid colors plus gradient options from both WordPress defaults and custom theme gradients.
Link colors add another layer with separate controls for default and hover states, giving you precise control over link styling throughout your block theme.
Don’t forget about Duotone – a lesser-known but powerful feature that applies color effects to images. You can create custom duotone filters or use WordPress defaults, though this only appears for image-containing blocks.
