For the first example here, the swatch goes from orange brown to a slightly more red brown. For the eye, they still look brown and are very similar. This would be OK!

For the second example, the swatch goes from yellow brown to orange brown and finally to red brown. Those colors are too much appart for the eyes and would not be accepted.

Exceptions:
- For bred evoloons, the colors must match the hue of one of the parent.
- For special evoloons with a color restriction like safari or chocolate, the colors must match the mandatory hue.
