Pastel designs have many different qualities. Some are more flat or soft, such as chalk pastels, or more pop art in feel, where the colour seems very dense and vibrant.
If you want the biggest effect from your choices, use pastel shades and texture together.
A flat pastel can work wonders in a modern wall for a bold effect, whilst using light pastels with a delicate texture or pattern can make them feel even softer. These soft pastel Duette® Shades give a variation to the quality of light that flows through them, creating a more unstructured, softer feel.
