Why Do My Colours Always Look Dull?

Having been painting and teaching for so many years I hear this all the time: “Why do my colours always look dull?”

Trust me, I’ve been there too, so I wanted to share why this might be happening and how to fix it.

It’s All About Context

First things first, the colours you place next to each other make a huge difference. Have you ever noticed how a colour can pop against a less saturated background?

Let’s look at Van Gogh’s “Café Terrace at Night.” See how that vibrant yellow just leaps off the canvas? It’s because he’s surrounded it with deeper, cooler tones. The contrast makes that yellow sing!

Too Much White Can Be a Mood Killer

When I first learned to paint, I assumed the only way to lighten a colour was to add white! I also assumed black was the only way to darken but that’s a whole other story.

But here’s the problem: white tends to flatten a colour and make it cooler, pushing it towards pastel territory. Instead, try using another colour to lighten.

For example, if you’re working with orange try adding a little yellow to brighten it up instead of white. When you do need to use a lot of white, try glazing over the top with a transparent colour. This adds depth and vibrancy that pure white can strip away.

Layering is Your Friend

Sometimes dull colours come from a lack of layering. Building up your colours in thin, transparent layers can create depth and richness that a single thick layer just can’t match. It takes more time, sure, but the results are worth it. Think of it like adding different spices to a dish – each layer brings something new to the mix.

Look at this piece by Turner: The Burning of the Houses of Lords and Commons, he used hundreds of layers to create depth and mood in his work.

Watch Out for Muddy Water!

Here’s a sneaky culprit – dirty water or brushes. If you’ve got a little colour left on your brush or in your water, it can contaminate your mix without you even realising it. Make sure you’re cleaning your brushes thoroughly between colours and changing your water regularly. It’s a small step that can make a big difference.

Embrace Complementary Colours

If you really want to make your colour pop try using complementary colours (opposite each other on the colour wheel) next to each other. A touch of purple next to yellow, or a bit of orange near blue can make both colours look more vibrant. Check out Monet’s “Water Lilies” series – see how he uses those little pops of complementary colours to bring the whole scene to life?

Quality Matters

I’ve seen over the years how much art materials have hugely increased in price. But investing in good quality pigments can make a world of difference. Cheaper paints often have more filler and less pigment, which can lead to duller colours. You don’t need to break the bank but treating yourself to a few high-quality colours can really elevate your work. I’ve even suggested to students you can use your cheaper paints for the initial layers or blocking in and then your better paints on top.

Don’t Forget About Lighting

Sometimes it’s not your painting – it’s your lighting!

In the past I would work long into the night as the sun went down (before kids lol!) and I’d come back the following day and the painting colour looked nothing like I’d left it! Very disappointing.

I would strongly suggest using natural daylight for seeing true colours. If you’re always painting under artificial light, try moving near a window or investing in a good daylight lamp. You might be surprised at how different (and vibrant) your colours look in the right light.

Remember, creating vibrant, lively colours is a skill that takes practice. Don’t get discouraged if your first attempts don’t turn out as bright as you’d hoped. Keep experimenting, keep observing how other artists use colour, and most importantly, keep painting!
