How standard are 'standard' RAL colours?

[HandyAndy]

hi Adrian...
alot depends on the actual colour you go for , you are correct in thinking that a RAL colour with the same code should be a good match with each other ......
but some colours are more sensitive than others ......

also ( i,m sure Fabby knows better than me ) but the way the person making the part can affect the depth of colour, i mean how much gelcoat is applied etc.

i should also say it can vary in the way the gel is supplied.... premixed or if the fabricator mixes it themselves with pigment,

what colours are you going for?

cheers
