RGBA to HSL Converter
RGBA (red-green-blue-alpha) and HSL (hue-saturation-lightness) are two different color models used to represent colors in digital graphics. RGBA represents a color using its red, green, blue, and alpha (transparency) values, while HSL represents a color using its hue, saturation, and lightness values.
To convert RGBA to HSL, you can use the following formulas:
First, convert the RGB values to a range of 0 to 1 by dividing each value by 255:
R' = R / 255
G' = G / 255
B' = B / 255
Then, find the maximum and minimum values of the R', G', and B' values:
Cmax = max(R', G', B')
Cmin = min(R', G', B')
Next, calculate the hue (H) value using the following formula:
If Cmax = Cmin, H = 0
Else if Cmax = R', H = 60 * ((G' - B') / (Cmax - Cmin)) mod 360
Else if Cmax = G', H = 60 * ((B' - R') / (Cmax - Cmin)) + 120
Else if Cmax = B', H = 60 * ((R' - G') / (Cmax - Cmin)) + 240
Note: the mod 360 is used to ensure that H is in the range of 0 to 360.
Then, calculate the lightness (L) value using the following formula:
L = (Cmax + Cmin) / 2
Finally, calculate the saturation (S) value using the following formula:
If Cmax = Cmin, S = 0
Else if L ≤ 0.5, S = (Cmax - Cmin) / (Cmax + Cmin)
Else if L > 0.5, S = (Cmax - Cmin) / (2 - (Cmax + Cmin))
Once you have calculated the H, S, and L values, you can convert them to hexadecimal values to get the corresponding HSL color code.
