OKLCH to HEX: #EFF6FF

Also known as: Tailwind blue-50, Tailwind v3 blue-50

oklch(0.97048 0.01418 254.604) → #EFF6FF

Values are shown at full precision, so converting back gives exactly #eff6ff. 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(0.97048 0.01418 254.604)
```

2. OKLCH → Oklab

a = C·cos H = -0.00376
b = C·sin H = -0.01367

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.966038
m′ = L − 0.1056·a − 0.0639·b = 0.971750
s′ = L − 0.0895·a − 1.2915·b = 0.988473

4. cube

l = 0.966038³ = 0.901534
m = 0.971750³ = 0.917623
s = 0.988473³ = 0.965816

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.863165
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.921581
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.999986

6. linear → sRGB, × 255

R = 0.93726 × 255 = 239.00 → 239
G = 0.96471 × 255 = 246.00 → 246
B = 0.99999 × 255 = 255.00 → 255

7. RGB → HEX
```
#EFF6FF
