I was excited when I found out about Murray Lancashire's colour constructor tool. Much, if not all, of my understanding of colour is based on a light based approach (additive mixing) and performing an initial render of three dimensional spheres based the local colour of the object before painting the complicated shape - a technique I learnt from Sam Nielson.
I wanted to understand more about the tool and about light in general by taking a photograph placing it in an entirely different lighting scenario.
I had taken this photograph a long time ago. It was chosen because I believe (perhaps erroneously!) that it wasn't too overexposed and taken in sufficiently neutral white light so that it would not obscure my estimation of the local colours of the dome or of the main building itself. Even if mistaken, the colour constructor tool should render spheres accurately based on my assumptions. It would just be a slightly inaccurate representation of the Tom Tower in Oxford!
The first lighting scenario I attempted was a dusky sunset, and the following is the set of spheres that the tool generated.
Exporting the swatches, I proceeded to illustrated the painting in the aforementioned lighting scenario. Here are the results.
I definitely enjoyed working with the tool and I believe I have learnt a fair bit about how the local colour changes is affected by the light sources.
I'm interested in seeing how Mr. Lancashire continues to develop the tool. There appears to be a provision to create your own masks (objects?) apart from a sphere and a cube. Though I'm not entirely sure, perhaps some reader of this blog will point me in the right direction!
