Step-by-step math

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

1. sRGB → linear

R: 216/255 = 0.84706 → 0.686685  (((x + 0.055) / 1.055)^2.4)
G: 180/255 = 0.70588 → 0.456411  (((x + 0.055) / 1.055)^2.4)
B: 254/255 = 0.99608 → 0.991102  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.578843
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.562631
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.813589

3. cube root

l′ = ∛0.578843 = 0.833400
m′ = ∛0.562631 = 0.825546
s′ = ∛0.813589 = 0.933544

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.82676
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.06420
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.08713

5. Oklab → OKLCH

C = √(a² + b²) = 0.10823
H = atan2(b, a) = 306.383°
L = 0.82676

6. OKLCH

oklch(0.82676 0.10823 306.383)
rounded: oklch(0.827 0.108 306.4)
