Phycobilins?

At Trentham Gardens today.

Red leaves on plants at Trentham Gardens today. Usually leaves are green but these have a strong red colour. The light shines through them giving them a glow. I remember hearing about other plant colours that happen in autumn. The green chlorophyll is absorbed back into the plant (usually a tree) and other underlying pigments that help to phosynthesise carbon dioxide and water to join together into simple sugars that can then be transformed into cellulose and other plant structures.

As the chlorophyll is absorbed, red phycobilins, yellow xanthophylls and orange carotenes are left in the leaves giving Autumn colours. This usually happens as the temperature cools and the plants start to store food and chemicals for winter.

I don’t know if these plants are doing thus? They remind me of the colours that are found in Swiss Chard.

Contour 4

Drawn this morning then mirrored and played with in photodirector. The idea is to draw a contour line around ink marks that have bled through from the previous page in my sketchbook. The initial drawing took a couple of hours, the duplication and mirrored images a few minutes. This is a combination of two lots of three images.

Fish

My watercolour of goldfish I did this April. I just came across this while I was looking back at my previous art.

I was talking to someone yesterday about letting white paper come through in watercolours. I rarely soak the paper before I start painting and I frequently mix up strong colours, leaving patches of white where I want to show light coming through. The way I think about it is that I can control the paint without having to use masking fluid… And it’s cheaper tgan using white paint or gouache.
