HEX to OKLCH: #FFF7ED

Also known as: Tailwind orange-50, Tailwind v3 orange-50

#FFF7ED → oklch(0.980 0.016 73.7)

Values are shown at full precision, so converting back gives exactly #fff7ed. 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: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)
G: 247/255 = 0.96863 → 0.930111  (((x + 0.055) / 1.055)^2.4)
B: 237/255 = 0.92941 → 0.846873  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.954638
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.935981
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.883844

3. cube root

l′ = ∛0.954638 = 0.984645
m′ = ∛0.935981 = 0.978188
s′ = ∛0.883844 = 0.959677

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.97962
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00443
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01514

5. Oklab → OKLCH

C = √(a² + b²) = 0.01577
H = atan2(b, a) = 73.684°
L = 0.97962

6. OKLCH

oklch(0.97962 0.01577 73.684)
rounded: oklch(0.980 0.016 73.7)
