Why colour tools?
Colour comes up everywhere in modern work: brand identity, web design, marketing graphics, dashboards, data viz, presentation decks. You'll constantly need to convert between formats (HEX for CSS, RGB for code, HSL for design adjustments, CMYK for print), build harmonious palettes for new projects, or pick exact colours out of existing images to match a brand.
