At this stage, I have under-painted some of the leaves with warm tones. The leaves will be various shades and tints of green, depending on the light, either reflected or refracted, but the warm undertones will add unity to the work. The underpainting is a relatively quick exercise, but the leaf detail will take longer. If I need highlights, I sometimes use a latex masking fluid, but I only put it on for a short time period because, in the sub-tropical ambient heat, the longer it remains on the paper, the more difficult it is to remove. My watercolour paintings take a while to complete, so the daily changes are not always evident, plus sometimes I just spend time observing before I commit paint to paper. Watercolour is not easy to change once applied.
