I have a Scalextric C4324 mk1 Escort.  The red paint adhesion is not good, and it is coming off the white base colour in multiple places.
I know I'm not going to get a perfect match, but I want to have a go at getting somewhere close.

The red is quite orange, if you understand what I mean.

I have Humbrol Acrylic 18 orange gloss and 19 bright red gloss.  The red is a bit too red, and the orange is far too orange to be anywhere near. To try and match the colour do I add a dash of red to some orange, or a dash of orange to some red?

Thanks in advance,
Stuart.

Pick the colour that is closer to the colour you want, probably red by the sound of it, then gradually add tiny amounts of the other and keep mixing.

I'd do a test run first with small amounts to see how it dries.

Colour mixing is an art. My dad was a master printer before he retired and grew up just to play golf. 

Besides black and white. There are three base colours from which most shades of anything are made. Red, blue, and yellow.

You'll need to add a lot of orange to make a dent in the red colour. Even then, it will not be very bright. If you want to make the red go towards bright orange/red. One drop of yellow does crazy things to a bottle of red.

Create a small test cup and see how quickly yellow changes red, into bright orange. Go very easy on the yellow. Little by little. You'll eventually find the shade you want.

Test twice. Paint once. Not the other way around.

KensRedZed has excellent advice and proper knowledge of color mixing, I can recall my early days of mixing PPG paints on the machine, and one drop goes a long way.

If all else fails, you can reach out to Paul at www.proscalepaints.uk - he most likely can make any color you want. He produced a custom Porsche color for me that is spot on.

Thank you all very much.  

I will let you know how I get on, if I remember.  ...........But it may be a while.

Red, Yellow, Blue...the 3 primary colours, as Ken said with Black & White the world's your rainbow oyster

I got lucky yesterday, but not with mixing.

I went to the model shop because I had run-out of Humbrol yellow acrylic.  Browsing the rack, I noticed no.132 satin red.  For the sake of £2.69, I decided to get one.  What do you know??  It's as close-a match as anyone is likely to get without using one of those machines that B&Q use to match household paint.  It just needs a coat of gloss lacquer.

But, this thread has jogged my memory about the intricacies of colour mixing.  Hopefully it will help others.
