Radix Red

Radix UI's red scale — 12 semantically labeled steps published in both light and dark variants. A balanced red suitable for error states and warm actions. Step 1 is app background, step 9 is the solid brand color, step 12 is high-contrast text. The same step number means the same semantic role across light and dark, with different hex values per mode.

Notes
Radix publishes distinct hex values for each scale in light and dark mode. This atom carries both as -light and -dark suffixed swatches; modes.light.roles points at -light swatches and modes.dark.roles at -dark swatches. Red is a chromatic hue and makes a poor neutral for body text, so steps 11 and 12 of Radix Slate are imported as supplementary swatches and used for text-primary and text-secondary in both modes.
