About this course

Explore the use of colour to achieve brilliance and vitality while painting flowers from the Walled Garden. Reference to historical and contemporary paintings reveal what makes a painting exuberant.

Course Description

Famous for their brilliant colours, dahlias are an excellent flower to study when it comes to colour mixing. Learn how to create the depth and brilliance of colour whilst making use of worksheets and sketchbooks.

Reference will be made to some outstanding examples of brilliant and dramatic use of colour that will encourage you to experiment. Simplified colour theories will be discussed and various watercolour techniques will be demonstrated, including dry brush and wet-in-wet. Complex ideas will be simplified to give you a better understanding of botanical painting. You will work at your own pace and individual guidance will be given.

Worksheets and sketchbooks will be used to learn and record your subject and techniques for future reference. This will help to establish good practice in your notation and recording. These references will also demonstrate the usefulness of record-keeping and being well organised when working from a fresh botanical specimen, especially when time is of the essence.

Through looking at examples of outstanding work and experimenting with ideas of your own, you will leave with a greater understanding of colour theory, colour mixing and application. It is unlikely, though not impossible, that you will leave with a completed painting, however, you will leave with valuable tools and studies with which to progress within your own practice.
