Spark plug

[Zackaryxr200boy]

I know this is a stupid question but can someone tell me what color a normal spark plug should be on a 1980 Honda xr200.

[Brainflex]

Same colour as a digestive biscuit on the tip that goes into the engine

[Akzle]

when?
porcelain white. spark blue.

They're a sort of purple paisley with orange highlights if I recall the 1980's correctly
