colour

A couple of weeks of colour theory. While I do not use colour much at the moment, understanding more about it should help me be more effective with what I do use.

Following a suggestion from an artist friend and playing with complementary colours, I painted up a piece of wood in violet and ultramarine to use as a base for the yellow/orange Uglow beakers (yellow-violet and orange-blue being compliments);

In theory, complementary colours should make each other brighter when placed next to each other. Not convinced by this example - to my eyes the yellows and oranges look most vivid on the plain white background. However, the strong ultramarine blue does lift the overall composition and look good next to the beakers. 

I was so focussed on taking the pictures that I did not really compare the set-ups visually, just set them up and took the pictures thinking I could compare on screen. However, I do not trust the camera completely as it was on auto and may have been adjusting factors to compensate for the colours. Although all pictures taken in same spot within 1 minute, they do look different and I think that when presented with a strong colour in the frame, the camera was overcompensating by making the overall picture lighter. More investigations, trusting my eye rather than the screen and manual camera settings needed...
