One of the things I’ve noticed is that people get very confused with the overtone of a colour and the undertone.
So to try and make it a little easier, I’ve created some pictures to help you see the differences between very similar colours, but one has a warm undertone, the other a cool undertone (even though they may all have a warm overtone).
Warm Overtone Colours and their Undertones
Can you see the differences? The warm colours have a touch of yellow in them (except the purple, which has a little more red, or should I say the cool has more blue). Click over the page for the cool overtones.
