Values are shown at full precision, so converting back gives exactly #c70036. 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(0.52538 0.21070 18.944)
```

2. OKLCH → Oklab

a = C·cos H = 0.19929
b = C·sin H = 0.06840

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.619127
m′ = L − 0.1056·a − 0.0639·b = 0.499975
s′ = L − 0.0895·a − 1.2915·b = 0.419206

4. cube

l = 0.619127³ = 0.237322
m = 0.499975³ = 0.124981
s = 0.419206³ = 0.073669

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.571115
G = −1.2684·l + 2.6098·m − 0.3413·s = -0.000002
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.036888

6. linear → sRGB, × 255

R = 0.78039 × 255 = 199.00 → 199
G = 0.00000 × 255 = 0.00 → 0
B = 0.21176 × 255 = 54.00 → 54

7. RGB → HEX
```
#C70036
```
