(inner) shiftColor(given, ref1, ref2) → {string}
Shifts a given color, using a reference pair (ref in HSL).
This algorithm ensures relative ordering on the saturation and luminance axes is preserved, and performs a simple hue shift.
It is also symmetrical. If: shiftColor(c, a, b) === d, then shiftColor(d, b, a) === c.
Parameters:
| Name | Type | Description |
|---|---|---|
given |
string | A hex color code to shift. |
