HEX to OKLCH: #FCE7F3

Also known as: Tailwind pink-100, Tailwind v3 pink-100

#FCE7F3 → oklch(0.948 0.028 342.3)

Values are shown at full precision, so converting back gives exactly #fce7f3. 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: 252/255 = 0.98824 → 0.973445  (((x + 0.055) / 1.055)^2.4)
G: 231/255 = 0.90588 → 0.799103  (((x + 0.055) / 1.055)^2.4)
B: 243/255 = 0.95294 → 0.896269  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.875969
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.846482
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.875711

3. cube root

l′ = ∛0.875969 = 0.956819
m′ = ∛0.846482 = 0.945960
s′ = ∛0.875711 = 0.956724

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.94820
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.02633
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00842

5. Oklab → OKLCH

C = √(a² + b²) = 0.02764
H = atan2(b, a) = 342.258°
L = 0.94820

6. OKLCH

oklch(0.94820 0.02764 342.258)
rounded: oklch(0.948 0.028 342.3)
