Values are shown at full precision, so converting back gives exactly #d2691e. 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. input
```
oklch(0.63440 0.15499 50.266)
```

2. OKLCH → Oklab

a = C·cos H = 0.09907
b = C·sin H = 0.11919

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.699388
m′ = L − 0.1056·a − 0.0639·b = 0.616331
s′ = L − 0.0895·a − 1.2915·b = 0.471602

4. cube

l = 0.699388³ = 0.342102
m = 0.616331³ = 0.234122
s = 0.471602³ = 0.104888

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.644478
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.141266
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.012987

6. linear → sRGB, × 255

R = 0.82353 × 255 = 210.00 → 210
G = 0.41177 × 255 = 105.00 → 105
B = 0.11767 × 255 = 30.01 → 30

7. RGB → HEX
```
#D2691E
