Sometimes I have trouble telling whether a color shade is warm or cool, especially navy blue and teal. Do you have any advice on how I can get better at it?

Determining whether a color leans warm or cool can be tricky, especially when the shade falls in between. Navy blue and teal are common examples where the undertone makes a big difference. Here are some ways to train your eye.

Understanding undertones

• Look for hints of red or orange. If the color leans that way, it’s probably warm.
• Colors with clear blue or green tones are usually perceived as cool.
• Navy blue can vary: some shades are neutral, others lean toward a warmer, slightly red undertone.

Test near the face

Hold the garment or fabric near your face in daylight:

1. Does the skin look lively and fresh? The color is likely closer to your own undertone.
2. Does the skin look pale or tired? The color is probably wrong for you.

This simple test works well for navy blue, teal, and other hard-to-judge colors.

Practice for better color perception

• Compare two shades at the same time – the differences become clearer.
• Study how the color changes next to neutral colors like gray or white.
• Use test swatches or a digital tool to see how the color harmonizes with your overall look.

With regular practice, it will become easier to tell whether a color is warm or cool, even in tricky tones like navy blue and teal.
