HEX to OKLCH: #FDF5E6

Result

Values are shown at full precision, so converting back gives exactly #fdf5e6. 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: 253/255 = 0.99216 → 0.982251  (((x + 0.055) / 1.055)^2.4)
   G: 245/255 = 0.96078 → 0.913099  (((x + 0.055) / 1.055)^2.4)
   B: 230/255 = 0.90196 → 0.791298  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.935338
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.914671
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.842473

3. 3. cube root

   l′ = ∛0.935338 = 0.977964
   m′ = ∛0.914671 = 0.970707
   s′ = ∛0.842473 = 0.944464

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.97234
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.00253
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.02141

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.02156
   H = atan2(b, a) = 83.264°
   L = 0.97234

6. 6. OKLCH

   oklch(0.97234 0.02156 83.264)
   rounded: oklch(0.972 0.022 83.3)
