Or you could do the smart thing and hire a designer that can sling front-end code worth a damn for $150k, and the feedback cycle becomes much cheaper and faster. "Let's see it in green" should take no more than 10 seconds, and can be done in-meeting.<p>As an aside, that sounds a lot like design-by-committee, which isn't known for producing the greatest results. If there are problems with the design (not branded enough, important button isn't emphasized enough, etc), then make sure that the point of the meeting is to <i>highlight those problems</i> and let the designer take care of the solutions later. If a (non-designer) founder is picking button colors, that founder isn't delegating properly.
