Colour relationships

This exercise looks at colour relationships. The idea is to produce a photograph for each combination of primary and secondary colours i.e. red : green ( 1:1),  orange : blue( 1:2) and yellow: violet ( 1:3). I found it very tricky to do as trying to capture images using the ratios above whether still life or found situations and in the particular colour combinations was no mean feat. In the first part of the exercise I have tried  to keep to the exact colour combinations :

Red : green  

P242: f13 @ 1/640 ISO 400 47mm -0.7exp.

Orange : blue

P243: f18 @ 1/60 ISO 100 30mm

Yellow : violet

P244: f14 @ 1/100  ISO 200 27mm

The following images are colour combinations that particularly appeal me ....

P245: f5.6 @ 1/500 ISO 100 54mm -0.3exp.

P245:  This simple colour combination struck me as quite dramatic in that the dark green of the foliage pushes out the yellow of the flowers and enables the two shades of yellow to stand out clearly.

P246:  I spotted this restaurant sign in a side street. I really liked  the contrast of the combination of a purple and red background to the pale yellow lettering stood out clearly on the bright yellow wall.

P247: When I started to look more carefully at colours and their various combinations and uses, I began to realise how how often red and yellow are used together to attract attention. Interestingly, more by way of emergency vehicles and working vehicles than high streen signage where combinations of blue and orande are more common, often within the 1: 2 ratio as well. The above Macdonalds sign is an exception ...I rather like the strident clash of colour softened a little by the textured red backround which almost shouts out at you... it serves its purpose well. However, the red and yellow combination below comes over more comfortably to the eye..artificial flowers echoing nature..
