HEX to OKLCH: #C6005C

Also known as: Tailwind pink-700

#C6005C → oklch(0.532 0.214 4.8)

Values are shown at full precision, so converting back gives exactly #c6005c. The rounded form is what you normally paste into CSS.

Step-by-step math

Every number below is computed from the input, nothing is looked up.

1. sRGB → linear

R: 198/255 = 0.77647 → 0.564712  (((x + 0.055) / 1.055)^2.4)
G: 0/255 = 0.00000 → 0.000000  (÷ 12.92)
B: 92/255 = 0.36078 → 0.107023  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.238292
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.131158
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.117288

3. cube root

l′ = ∛0.238292 = 0.619969
m′ = ∛0.131158 = 0.508080
s′ = ∛0.117288 = 0.489498

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.53170
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.21294
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01793

5. Oklab → OKLCH

C = √(a² + b²) = 0.21370
H = atan2(b, a) = 4.812°
L = 0.53170

6. OKLCH

oklch(0.53170 0.21370 4.812)
rounded: oklch(0.532 0.214 4.8)
