For this exercise I used a coloured path marker and filled the frame with it. In real life the marker looked a striking blue although in the photographs the colour is far more washed out.

The pictures were all take with an iso setting of 100 and a shutter speed of 1/400.
F10 looks nearest to the colour that I pictured when I was looking at the object with just my eye. As the aperture gets higher the colours in the pictures darken and as the aperture widens the colours get lighter.
