How to Verify stock injectors

[Rawpwr7]

I would like to know what color stock injectors are. Mine are Red and it seems like my truck is running rich. I have a A/F gauge(I know they are not reliable) when I floor the gas the A/F gauge riches up. Also I am getting crapy gas mileage like 10mpg. Is that correct...All is stock except ATR intake, ATR Exhaust.
thank you

get a datamaster.
maybe your O2 sensor is fucked.
and there are a whole bunch of other stuff that can cause it to run to rich
