Also known as: CSS darkturquoise

oklch(0.77193 0.13144 196.643) → #00CED1

Values are shown at full precision, so converting back gives exactly #00ced1. 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(0.77193 0.13144 196.643)
```

2. OKLCH → Oklab

a = C·cos H = -0.12593
b = C·sin H = -0.03765

3. Oklab → LMS′

l′ = L + 0.3963·a + 0.2158·b = 0.713894
m′ = L − 0.1056·a − 0.0639·b = 0.787628
s′ = L − 0.0895·a − 1.2915·b = 0.831818

4. cube

l = 0.713894³ = 0.363832
m = 0.787628³ = 0.488610
s = 0.831818³ = 0.575552

5. LMS → linear sRGB

R = 4.0767·l − 3.3077·m + 0.2310·s = 0.000001
G = −1.2684·l + 2.6098·m − 0.3413·s = 0.617210
B = −0.0042·l − 0.7034·m + 1.7076·s = 0.637596

6. linear → sRGB, × 255

R = 0.00001 × 255 = 0.00 → 0
G = 0.80784 × 255 = 206.00 → 206
B = 0.81961 × 255 = 209.00 → 209

7. RGB → HEX
```
#00CED1
