Color Models & Spaces — At a Glance
RGB (additive) and CMYK (subtractive) target different devices; HSL/HSV re-express RGB for more intuitive manipulation.
RGB/HEX/HSL/HSV conversions are deterministic; CMYK mappings vary with ICC profiles (e.g., sRGB ↔ coated CMYK).
Device color spaces (sRGB, Display-P3) define gamut; color-managed pipelines reduce visual discrepancies across devices.
Frequently Asked Questions
Q.What's the difference between RGB and CMYK color models? When should I use each?
A. RGB (additive light) is for screens; CMYK (subtractive ink) is for print. Use RGB/HEX for web and CMYK for professional printing.
Q.What is HEX color code and how does it relate to RGB?
A. HEX is a base-16 notation for RGB as #RRGGBB (e.g., #FF5733). It represents the same color as rgb(255,87,51) in a different format.
Q.What is HSL and why is it more intuitive than RGB for color adjustments?
A. HSL separates Hue, Saturation, and Lightness, making tints, shades, and palette tweaks more intuitive than raw RGB channel edits.
Q.Are color conversions between formats accurate? What about RGB to CMYK?
A. RGB ↔ HEX ↔ HSL/HSV conversions are mathematical and exact. RGB → CMYK is approximate and depends on printer/paper ICC profiles—treat it as a preview.
