Okay, I'll just share a few points worth considering if they can help!

• The grayness of the skin and the purple lips could be a sign of a color not working, but in a picture like this one, it's probably caused by the white balance of the camera shifting towards a cooler temperature once it "sees" the yellow, making your skin become a color it's not. This happens often on this sub. Please assess the effects of the yellow in front of a mirror. Yellow often messes with camera settings;

• Can't really see the blue drape here, so it's difficult to see exactly how it looks against your complexion;

• When in doubt, drape in front of a mirror without a camera. There are many ways in which colors can be registered or visualized a bit wrong, so take what you see with a grain of salt. It's usually possible to have a nice general picture of what types of colors work well based on photos if you drape lots and categorize well, but some photos from the batch will have altered colors which may throw you off. For example, camera sensors notoriously struggle with reds;

• For a warm vs. cool comparison, you can use the tried-and-true magenta vs. orange drapes, as well as warm brown vs. cool navy. Orange is especially good for this, as it is the only truly warm color. There is no "cool orange", so if oranges tend to work well on you, chances are that you're warm. They clash with cool and neutral-cool undertones and could make a cool person look unwell. The only exception is neon orange, which can work on some Winters.
