Quick Summary & Direct Answer

Digital screens produce colors via additive RGB channels (Red, Green, Blue from 0 to 255), which are represented in web development as Hexadecimal (#RRGGBB) or HSL (Hue, Saturation, Lightness). Physical print uses subtractive CMYK inks. The Sys-Metrics Color Studio ensures mathematically accurate translations and flags non-accessible low-contrast color combinations to ensure ADA and WCAG 2.1 compliance.
