HEX to OKLCH: #024A70

Result

Values are shown at full precision, so converting back gives exactly #024a70. 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: 2/255 = 0.00784 → 0.000607  (÷ 12.92)
   G: 74/255 = 0.29020 → 0.068478  (((x + 0.055) / 1.055)^2.4)
   B: 112/255 = 0.43922 → 0.162029  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.045313
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.064143
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.121420

3. 3. cube root

   l′ = ∛0.045313 = 0.356512
   m′ = ∛0.064143 = 0.400298
   s′ = ∛0.121420 = 0.495181

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.39070
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.04385
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.07786

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.08936
   H = atan2(b, a) = 240.611°
   L = 0.39070

6. 6. OKLCH

   oklch(0.39070 0.08936 240.611)
   rounded: oklch(0.391 0.089 240.6)
