Formule & Méthode de Calcul
RGB(r,g,b) ➔ Teinte ➔ Saturation ➔ Luminosité ➔ Tableau de format de base
Converting between spaces requires floating point math. For example, converting RGB to HSL requires identifying the maximum and minimum RGB values to calculate perceived luminance before extracting the angular hue.
Bonnes Pratiques & Conseils
- Use CMYK for Physical Print: The RGB color space uses emitted light, meaning it can create neon, hyper vibrant colors that are physically impossible to replicate using CMYK ink on paper. Always convert and preview in CMYK before printing.
- Use Complementary Schemes for Call to Actions (CTAs): A complementary color sits directly across the color wheel. If your brand is primary Blue, a complementary Orange button will create the highest possible optical contrast.
- Beware of Saturation Traps in HSL: Scaling the lightness down in HSL while keeping saturation at 100% often creates muddy, hyper saturated colors. Pro designers naturally decrease saturation slightly as colors get darker.
