HEX to OKLCH: #0E7490

Result

Values are shown at full precision, so converting back gives exactly #0e7490. 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. 1. sRGB → linear

   R: 14/255 = 0.05490 → 0.004391  (((x + 0.055) / 1.055)^2.4)
   G: 116/255 = 0.45490 → 0.174647  (((x + 0.055) / 1.055)^2.4)
   B: 144/255 = 0.56471 → 0.278894  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.109827
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.149765
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.225287

3. 3. cube root

   l′ = ∛0.109827 = 0.478891
   m′ = ∛0.149765 = 0.531052
   s′ = ∛0.225287 = 0.608478

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.51976
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.06829
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.06396

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.09357
   H = atan2(b, a) = 223.128°
   L = 0.51976

6. 6. OKLCH

   oklch(0.51976 0.09357 223.128)
   rounded: oklch(0.520 0.094 223.1)
