-# Updated neutral base color scales
-
-## Changes
-
-- Theme specific neutral scales have been replaced with two new scales: `light` and `dark`.
-- The new `light` and `dark` scales are inverted, where 0 is the lightest shade in `light` and the darkest shade in `dark`.
-- Functional color tokens have been updated to use the new `light` and `dark` scales, and several overrides have been removed due to the new inverted design.
-
-## Migration
-
-- Functional color tokens all work as expected and have been tested to meet minimum contrast requirements.
-- If you are using `primer/primitives` base color scales directly, you may need to update how those colors are applied. See the migration table which outlines approximately how the new colors map to the old colors.
