How do i find the ral colour for my car its a blue focus mk1?

 

There may not be an exact RAL colour match for your car, in fact it's very unlikely. The RAL colour codes are just codes for a specific range of German colours. A paint company like Cromadex will have RAL colour charts so you can compare them to your car and pick the nearest match. May well not be close enough to use as a match though.
