All scouters are green. Zarbon and Dodoria were never shown in full-color pages, however Ginyu Force scouters (including Freeza's) are:

(in the second page it might look blue, however that's the color transparency, look at the eyes)
And a true inconsistency occur when Jeice gives Ginyu a yellow scouter (however before that we already saw all Ginyu Forces scouters are green)

Besides that, in all gray & red tones pages the scouters are colored grayish (or brownish in rare cases).
