i want to put 3 gauges in my dash but im going to have to cut and blend pod in, i did this a while ago and just fibreglassed it in at the back but looked tacky

so im going to do it properly now buthave no idea of the colour its sort of a dark metallic grey

anyone got a rough idea what would come close or am i going to have to go down paint suppliers nxt week

easier to ask here first lol
