HEX to OKLCH: #C4B5FD

Result

Values are shown at full precision, so converting back gives exactly #c4b5fd. 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: 196/255 = 0.76863 → 0.552011  (((x + 0.055) / 1.055)^2.4)
   G: 181/255 = 0.70980 → 0.462077  (((x + 0.055) / 1.055)^2.4)
   B: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.525911
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.536999
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.797717

3. 3. cube root

   l′ = ∛0.525911 = 0.807181
   m′ = ∛0.536999 = 0.812814
   s′ = ∛0.797717 = 0.927434

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.81116
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.04050
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = -0.09284

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.10129
   H = atan2(b, a) = 293.571°
   L = 0.81116

6. 6. OKLCH

   oklch(0.81116 0.10129 293.571)
   rounded: oklch(0.811 0.101 293.6)
