Yes, the the high and the low beams would each have their same color on both sides, as the same beams of both sides are immediately connected in parallel on their way to the low-side control circuitry. What would be a different color is the common plus, since each side is fed through a separate circuit. And the common terminal is on the right side of the connector (looking into it) on every diagram I've ever found. Try a Google search on H4 Pinout.
PM me your e-mail address and I'll send you a diagram.
