HEX to OKLCH: #B0C4DE

Result

Values are shown at full precision, so converting back gives exactly #b0c4de. 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: 176/255 = 0.69020 → 0.434154  (((x + 0.055) / 1.055)^2.4)
   G: 196/255 = 0.76863 → 0.552011  (((x + 0.055) / 1.055)^2.4)
   B: 222/255 = 0.87059 → 0.730461  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.512608
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.546202
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.654024

3. 3. cube root

   l′ = ∛0.512608 = 0.800317
   m′ = ∛0.546202 = 0.817431
   s′ = ∛0.654024 = 0.868023

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.81362
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = -0.01106
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.04136

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.04281
   H = atan2(b, a) = 255.033°
   L = 0.81362

6. 6. OKLCH

   oklch(0.81362 0.04281 255.033)
   rounded: oklch(0.814 0.043 255.0)
