booster line clips

the flexible line that connects the booster fitting to the vacuum line on the engine is attached with a clip on each end, does anyone know what color these are supposed to be??? 3/8" line works (ie so olive green) but it looks like the factory line was a much larger OD and clamps may have been black??

Thanks

Tim,
That hose did have a larger ID and the clips were black.
