Step-by-step math

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

1. sRGB → linear

R: 218/255 = 0.85490 → 0.701102  (((x + 0.055) / 1.055)^2.4)
G: 178/255 = 0.69804 → 0.445201  (((x + 0.055) / 1.055)^2.4)
B: 255/255 = 1.00000 → 1.000000  (((x + 0.055) / 1.055)^2.4)

2. linear sRGB → LMS

l = 0.4122·R + 0.5363·G + 0.0514·B = 0.579231
m = 0.2119·R + 0.6807·G + 0.1074·B = 0.559011
s = 0.0883·R + 0.2817·G + 0.6300·B = 0.817309

3. cube root

l′ = ∛0.579231 = 0.833586
m′ = ∛0.559011 = 0.823772
s′ = ∛0.817309 = 0.934965

4. LMS′ → Oklab

L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.82538
a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.06952
b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.08967

5. Oklab → OKLCH

C = √(a² + b²) = 0.11346
H = atan2(b, a) = 307.786°
L = 0.82538

6. OKLCH

oklch(0.82538 0.11346 307.786)
rounded: oklch(0.825 0.113 307.8)
