How to Use the Color Inverter & Exact Complement Calculator
-
1
Enter any color in HEX or RGB format.
-
2
View Mode 1: Photographic Inversion (RGB Negative: `255 - R, 255 - G, 255 - B`).
-
3
View Mode 2: Color Wheel Complement (exact 180° Hue rotation in HSL space, preserving saturation and lightness).
-
4
Compare original and inverted colors side by side with contrast ratio metrics.
Practical Example & Use Case
Common Real-World Scenario
Finding that the exact color wheel complement of pure Royal Blue (`#0033cc`, Hue 225°) is Golden Amber (`#cc9900`, Hue 45°).

Frequently Asked Questions
Why is RGB negative inversion different from a complementary color?
RGB negative flips lightness (black becomes white); a true complementary color rotates hue by 180° while retaining the original lightness level.
