Notes

Light Slate Gray is a mid-light blue-gray with enough chroma to read as cool rather than fully neutral. The CSS hex sits in the territory of modern UI mid-grays used for secondary text and borders. Editorial, business, and tech designs use it for de-emphasized text or panel backgrounds. Pair with charcoal for primary text and a single warm accent. Against white it carries enough contrast for secondary text at body sizes but should be checked for AA compliance. Body text contrast against white passes AA at standard body sizes; AAA holds only at headline sizes.
