Step-by-step math

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

1. 1. sRGB → linear

   R: 34/255 = 0.13333 → 0.015996  (((x + 0.055) / 1.055)^2.4)
   G: 41/255 = 0.16078 → 0.022174  (((x + 0.055) / 1.055)^2.4)
   B: 43/255 = 0.16863 → 0.024158  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.019729
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.021078
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.022878

3. 3. cube root

   l′ = ∛0.019729 = 0.270212
   m′ = ∛0.021078 = 0.276233
   s′ = ∛0.022878 = 0.283883

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.27493
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.00846
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.00634

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.01058
   H = atan2(b, a) = 216.852°
   L = 0.27493

6. 6. OKLCH

   oklch(0.27493 0.01058 216.852)
   rounded: oklch(0.275 0.011 216.9)
