Is your spark plug color the same on all cylinders?

I'm having a problem with my left side (1,2,3) burning much leaner than the right. I've tried adding more fuel to the left, but so far it hasn't fixed it . The fuel rails are in series with the left getting fuel first, so I don't think it's fuel starved. My tuner's thinking it may be cam timing, so I get to check that this weekend.
