Exercise: Colour Relationships - Part 2

For the second part of this exercise, i was asked to produce 3 or 4 photographs of colour combinations that appeal to me.
I quite liked the freedom of this part of the task not really having any rules, being able to photograph whatever colours / subjects i want.

A Green glass head against a pinky /violet background. I struggled to get a true, bright green colour out of the head with it being see through, however i am happy with the shade of green i managed to capture and how it appears more of a lime colour where the light hits it. However against the pinky less saturated shade of violet is is set against, i feel it works.
Pink and green. my favourite colour combination.

I quite like a combination of similar colours. Here yellow,green, and blue, three colours that are adjacent to each other on the colour wheel. I like that the yellow is a lot more bolder and attention grabbing than the other two colours present.

Here i took a picture of a large yellow sign and a smaller, blue ticket machine behind it. Two colours that are spaced out on the colour wheel. Two bold colours that as a combination would perhaps be seen as clashing.

Red and yellow, again two colours spaced out on the colour wheel. A combination often associated with fire or heat/warmth.
