Colors not accurate when converting colors from hsl > rgb when calling triadic and tetradic functions

[tylerguy]

When converting from a HSL to RGB color whenever getTriadicColor and getTetradicColor are called, rgb values end up being either 1 higher or lower.

Few test cases to check
#ec0ffd - should return [ 253, 236, 15 ], [ 15, 253, 236 ], but returns [ 253, 237, 15 ], [ 15, 253, 237 ]
#ec0ffe - should return [ 254, 236, 15 ], [ 15, 254, 236 ] but returns [ 254, 234, 15 ], [ 15, 254, 234 ] (this is more of a difference than previously observed)
