OKLCH to HEX: #082F49

Result

Values are shown at full precision, so converting back gives exactly #082f49. 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. input

   oklch(0.29346 0.06324 243.157)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.02856
   b = C·sin H = -0.05643

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.269965
   m′ = L − 0.1056·a − 0.0639·b = 0.300077
   s′ = L − 0.0895·a − 1.2915·b = 0.368888

4. 4. cube

   l = 0.269965³ = 0.019675
   m = 0.300077³ = 0.027021
   s = 0.368888³ = 0.050198

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.002428
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.028427
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.066629

6. 6. linear → sRGB, × 255

   R = 0.03138 × 255 = 8.00 → 8
   G = 0.18432 × 255 = 47.00 → 47
   B = 0.28628 × 255 = 73.00 → 73
