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.
