OKLCH to HEX: #1447E6

Result

Values are shown at full precision, so converting back gives exactly #1447e6. 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(0.48778 0.24322 264.405)

2. 2. OKLCH → Oklab

   a = C·cos H = -0.02371
   b = C·sin H = -0.24206

3. 3. Oklab → LMS′

   l′ = L + 0.3963·a + 0.2158·b = 0.426144
   m′ = L − 0.1056·a − 0.0639·b = 0.505740
   s′ = L − 0.0895·a − 1.2915·b = 0.802521

4. 4. cube

   l = 0.426144³ = 0.077387
   m = 0.505740³ = 0.129354
   s = 0.802521³ = 0.516855

5. 5. LMS → linear sRGB

   R = 4.0767·l − 3.3077·m + 0.2310·s = 0.006998
   G = −1.2684·l + 2.6098·m − 0.3413·s = 0.063010
   B = −0.0042·l − 0.7034·m + 1.7076·s = 0.791274

6. 6. linear → sRGB, × 255

   R = 0.07845 × 255 = 20.01 → 20
   G = 0.27843 × 255 = 71.00 → 71
   B = 0.90195 × 255 = 230.00 → 230
