HEX to OKLCH: #CAD5E2

Also known as: Tailwind slate-300

#CAD5E2 → oklch(0.869 0.022 252.5)

Values are shown at full precision, so converting back gives exactly #cad5e2. 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: 202/255 = 0.79216 → 0.590619  (((x + 0.055) / 1.055)^2.4)
G: 213/255 = 0.83529 → 0.665387  (((x + 0.055) / 1.055)^2.4)
B: 226/255 = 0.88627 → 0.760525  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.639461
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.659761
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.718719

3. cube root

l′ = ∛0.639461 = 0.861532
m′ = ∛0.659761 = 0.870554
s′ = ∛0.718719 = 0.895749

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.86855
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00649
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.02061

5. Oklab → OKLCH

C = √(a² + b²) = 0.02161
H = atan2(b, a) = 252.514°
L = 0.86855

6. OKLCH

oklch(0.86855 0.02161 252.514)
rounded: oklch(0.869 0.022 252.5)
