Among the provisions in the big taxi reform bill set to be unveiled today is a solitary color for all city cabs. This has been a longstanding dream of the hospitality industry, which argues that it would make cabs easier to spot, more accessible for tourists and that it might set the tone for further service mandates.

The industry has resisted the suggestion, however. A 2008 task force on taxi industry reform rejected the idea, saying paint color “is a major part of each company or association’s identity and service brand. It is through the color recognition and service that the public makes an informed choice on what company or association’s service to use.”

But now it appears there is some political heft behind color consolidation. So what color?

The bill’s sponsor, Mary Cheh (D-Ward 3) wants Boston white:

Others, including Tommy Wells (D-Ward 6), have suggested the same shade of crimson now sported by Circulator buses, Capitol Bikeshare and the coming streetcar. Let’s call it DDOT red:
