Inspectors should not "give you grief" for using blue and white wires as shown here. (Inspectors are volunteers and volunteers are at the event to help teams, not to give them grief.) Per <R54> blue is OK for common circuits and white is OK for 12V. However, the use of these colors is not very common in FIRST, so you should be prepared to show your inspector the rule in case he/she has not seen this before.

All wires distributing power with a constant polarity (i.e., except for relay module, speed controller, or sensor outputs) shall be color-coded as follows:
• Use red, white, or brown wire for +12 Vdc and +5 Vdc connections.
• Use black or blue wire for common (-) connections.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
