Primary and secondary colours

The requirement of this exercise is to find a scene or scenes dominated by a one of the six single colours of the primary or secondary category:-

 

Colour Wheel

Originally I had in mind selecting part of the high street and take colour swabs so to speak of what I saw there.  Another idea was to go in a shop and see if I could get the full range in there.  I also had the idea of seeing what options were closer to home and thought it might be interesting to do an experiment and see if I could identify, or at least get close to, the colours in the circle on a macro level.  Its interesting to note that on my, calibrated, monitor the six colours are much more distinct than the printed version.  I chose the bathroom to do this as such colour there is in there, is on a relatively small scale:-

Detail of label F2.8 @ 1/15 ISO200 (exposed as +.7 stop)

Of the three above I thought the last one is an approximation of the violet in the circle but at the time I was shooting I was using a printed version of the circle and now on examination its not as close as I thought it was!

F2.8 @ 1/6 ISO200 (exposure increased by .7 stop)

In the case of the blue I think the underexposed version is a much closer match.

For red I used a bottle cap:

DSC08325

Bottle cap F3.2 @ 1/8 ISO200 overexposed at .7 stop.

To my eyes this time the overexposed shot comes very close to the circle colour.

The Orange I found was the interior of a wash bag.

The yellow was a detail from the artificial flower on the windowsill

To my eyes the very edge of the petal is the closest to the yellow but, interestingly, the out of focus area on the right hand side is also a good match in this shot.

For the green I used a shampoo bottle.  This was quite reflective and because of its position in the bathroom one edge was more in shadow so there was a difference in the shade of green straight away.:-

DSC08307

Of the three shots I think the right hand shade of the overexposed shot is the closest although, as the course book indicates, there is a lot of variance in green!

I found this a useful exercise as my colour sense is not particularly strong in terms of identifying shades and is something worth developing or practising.
