Squares on squares - seeing how colours interrelate and how a neighbouring colour affects the way we see the colours around it.
This was my first version with small central squares in grey:
And version two with larger central squares in green
And version three - central squares in yellow:
Thoughts:
It would be interesting to do this exercise again with different colour backgrounds to see how this affects the relationship between the inner and outer squares.
As an extra exercise I tried manipulating these images in Photoshop by converting them to black and white to see what the contrasts look like when removing the colour aspect. Here are the results.
What is interesting about this is that the pink (bottom left image 2 and 2nd from left image 3) is almost exactly the same tone as the central mint/yellow square which was surprising. The reds produced the strongest contrasts which I would have expected. The grey centre squares offered very little contrast with the outer squares when seen in black and white. The mint and yellow contrasted more strongly.
