The next stage after the white flower is coloured flowers. But these bougainvillea are a real challenge, as they have so many colours. Again, the best strategy is to do a tonal study, and take a black and white photo to help you.
You can see that the tones are much more subtle than they were in the case of the white rose. The red flower is a much darker tone, even though it’s a bright colour. And the delicate veins stand out as dark lines, but they must not be too strongly emphasised.
As I did with the rose, I use a basic colour to indicate the lightest parts of each flower. I’m working on a neutral dark grey paper.
I tried working on the textured side of the paper first, but I just don’t find it works for me. Here I’m using a make up tool to blend the colours, but the little pits in the paper still keep coming back and creating a texture I don’t want!
This is the final version on the smooth side of the paper. I used dark green (the complementary of red) and black behind the flower to make the pink glow even more. I’ve only slightly indicated the veins in the petals, and I used blue on the upper right petal to help indicate that it is receding from view, while the petal on the left is coming towards the viewer so I used warmer, lighter colours. I have left the background flowers unfinished, as I like them just as they are.
