According to one study at least, warm yellowish-hued LED light attracted the fewest bugs. The study wasn't about crickets specifically though and different bugs seem to respond to different lights. The warm hued LED was the overall winner.

Note the study was intended for the bug's benefit (e.g. ecological effects of light pollution) and not humans, but attracting fewer bugs should benefit both either way. It also isn't yet peer-reviewed but was credible enough to be presented at the American Association for the Advancement of Science conference.

This is the first study to directly compare all the major types of bulbs designed for exterior residential use. A widespread shift to LED lamps could greatly reduce the impact of light pollution on insects. From an ecological perspective, LEDs with a warm color temperature should be favored because they attract the fewest insects, their lower emission in the blue spectrum should reduce their contribution to light pollution, their directional technology allows for more precise lighting, and they have favorable energy conversions and life cycle assessments.
In general no light, or very low light would still attract fewer than any other possibility but you may be on to something.
