HEX to OKLCH: #BC8F8F

Result

Values are shown at full precision, so converting back gives exactly #bc8f8f. 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: 188/255 = 0.73725 → 0.502886  (((x + 0.055) / 1.055)^2.4)
   G: 143/255 = 0.56078 → 0.274677  (((x + 0.055) / 1.055)^2.4)
   B: 143/255 = 0.56078 → 0.274677  (((x + 0.055) / 1.055)^2.4)

2. 2. linear sRGB → LMS

   l = 0.4122·R + 0.5363·G + 0.0514·B = 0.368750
   m = 0.2119·R + 0.6807·G + 0.1074·B = 0.323036
   s = 0.0883·R + 0.2817·G + 0.6300·B = 0.294829

3. 3. cube root

   l′ = ∛0.368750 = 0.717096
   m′ = ∛0.323036 = 0.686146
   s′ = ∛0.294829 = 0.665564

4. 4. LMS′ → Oklab

   L = 0.2105·l′ + 0.7936·m′ − 0.0041·s′ = 0.69274
   a = 1.9780·l′ − 2.4286·m′ + 0.4506·s′ = 0.05194
   b = 0.0259·l′ + 0.7828·m′ − 0.8087·s′ = 0.01745

5. 5. Oklab → OKLCH

   C = √(a² + b²) = 0.05480
   H = atan2(b, a) = 18.565°
   L = 0.69274

6. 6. OKLCH

   oklch(0.69274 0.05480 18.565)
   rounded: oklch(0.693 0.055 18.6)
