There’s something really satisfying about seeing your car in a colour that isn’t straight from the manufacturer’s brochure. Maybe you want a deeper blue, a warmer grey, or a red with a bit more character. Whatever the vision, creating your own custom shade doesn’t have to cost a fortune.
With a bit of patience, careful testing, and the right approach, mixing your own car paint can be both affordable and hugely rewarding. Let’s walk through how to do it properly - without wasting money or ruining your finish.
Why Mix Your Own Paint in the First Place?
DIY colour mixing gives you a few real advantages:
- You’re not limited to off-the-shelf colours
- It’s cheaper than ordering a factory custom shade
- You can recreate the same mix later for touch-ups
- You get complete creative control
And honestly, there’s also that quiet sense of pride when someone asks, “What colour is that?” and you can say, “I mixed it myself.”
Start with the Right Base Colour
Every custom colour starts with a base paint. Choose one that’s already close to what you’re aiming for - it’ll save you time, money and frustration.
If you’re new to mixing:
- Stick to solid (non-metallic) colours at first
- Avoid jumping straight into pearls and heavy metallics
- Use automotive paint designed for mixing, not decorative paint
A quick real-world example
One DIYer wanted a deep wine red but only had a bright standard red. Instead of starting from scratch, they slowly added tiny amounts of black over several test mixes. By the third attempt, the colour was spot on - and no paint was wasted.
What Each Colour Additive Actually Does
This is where most people slip up - adding too much, too quickly.
Here’s a simple guide:
- White – Lightens and softens
- Black – Darkens and deepens
- Yellow – Warms a colour
- Blue – Cools it
- Red – Adds richness
- Pearl or metallic flakes – Add depth and light reflection
Golden rule:
Always add darker colours in tiny amounts. You can always add more - but you can’t take it back out.
Always Mix Small Test Batches First
Never mix a full tin straight away. This is how money gets wasted.
Instead:
- Mix a small amount (100–200ml)
- Adjust your shade gradually
- Stir thoroughly
- Spray onto a test card or spare panel
- Let it dry fully before judging the colour
This approach:
- Saves paint
- Helps you perfect the colour first
- Avoids expensive mistakes on the actual car
Lighting Will Change Everything
Your paint will never look the same under all lighting.
Always check your test colour:
- In daylight
- In shade
- Under your garage lights
That clean grey in the garage might look blue outside. A red might turn orange in bright sun. This step alone prevents a lot of regret.
Keep a Proper Mixing Record
This might seem boring - but it’s one of the most important DIY habits you can build.
Write down:
- Base colour used
- Every additive added
- Exact quantities
- Final mixing ratio
Why it matters:
- You can remake the colour exactly
- Touch-ups will match
- No guesswork next time
Don’t Forget: Clearcoat Changes the Final Look
A lot of people panic after spraying their base colour because it doesn’t look “right”. Then the clearcoat goes on - and suddenly the colour comes to life.
- Deepens colour
- Adds gloss
- Enhances metallics and pearls
- Slightly darkens darker shades
Always test your colour with clearcoat applied, not just the raw base.
Where Most DIYers Lose Money (So You Don’t)
Avoid these common mistakes:
- Mixing full tins without testing
- Not writing down ratios
- Judging colour before clearcoat
- Rushing drying times
- Using products that don’t work well together
Patience is always cheaper than repainting.
Is DIY Colour Mixing Right for You?
DIY mixing is ideal if you:
- Want a one-of-a-kind shade

- Are working within a budget
- Plan to do future touch-ups
It may not suit you if:
- You need an exact factory colour match
- You’re repainting a high-value vehicle
- You don’t have a clean, controlled spraying space
