Picks the color for pixel (x, y).
The first color fades into the second color as you move from the initial fill point, the center, to the radius. Beyond the radius, all pixels should be just color2.
You should calculate the distance between two points using the standard euclidean distance formula.
Then, scale each of the three channels (H, S, and L) from color1 to color2 linearly from d = 0 to d = radius.
x | The x coordinate to pick a color for. |
y | The y coordinate to pick a color for. |
Implements ColorPicker.
