Quick watercolour sky with Charles Evans

British artist and teacher Charles Evans demonstrates just how simple and fast it can be to paint a watercolour sky with clarity and ease. All he uses are two brushes – a ¾‑inch flat and an 8 round – and just two colours, Ultramarine Blue and Burnt Sienna, both from the Aquafine range. His key advice, above all, is not to hesitate when it comes to wetting the paper with plenty of water.

Simple Steps for a Quick Sky

• Use plenty of water to prepare your paper – it’s essential for achieving soft, natural transitions.

• Apply a ¾‑inch flat brush with a mix of Burnt Sienna and Ultramarine Blue, allowing the colours to merge freely in the wet surface.

• Soften the form of the sky by blending with the 8 round or a washed-out brush – minimal precision, maximum effect.

This technique is perfect for beginners who want to explore how watercolour fluidity can create mood quickly. It’s also ideal for artists seeking a simple yet impactful method that doesn’t rely on a full palette or complex tools.

Why This Approach Works

The magic lies in the simplicity; two colours, two brushes, and a bold approach to wetness. The generous water encourages soft gradients and expressive strokes, making it easier to achieve a convincing sky in just a few moves. It’s a great way to build confidence in handling wash and waterflow, and to invite spontaneity back into your work.
