Values are shown at full precision, so converting back gives exactly #a3b3ff. 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(0.78327 0.11003 274.474)
```

2. OKLCH → Oklab

a = C·cos H = 0.00858
b = C·sin H = -0.10969

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.762999
m′ = L − 0.1056·a − 0.0639·b = 0.789368
s′ = L − 0.0895·a − 1.2915·b = 0.924171

4. cube

l = 0.762999³ = 0.444194
m = 0.789368³ = 0.491857
s = 0.924171³ = 0.789327

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.366251
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.450784
B = −0.0042·l − 0.7034·m + 1.7076·s = 1.000021

6. linear → sRGB, × 255

R = 0.63921 × 255 = 163.00 → 163
G = 0.70196 × 255 = 179.00 → 179
B = 1.00000 × 255 = 255.00 → 255

7. RGB → HEX
```
#A3B3FF
```
