I did mine a little while back. No kit - it's always been cheaper for me to just buy big bags of stuff; I have done several games and just needed a lot of bulbs. I do put some color matched bulbs occasionally (mostly blue and yellow). Red you just need to get the right level of brightness on the LED - too bright, and it can look orange. Cool white for inserts. Warm white for GI.
There's almost no need to do color matching really, though - mine has LEDOCD and GIOCD installed - those are much better value than trying to match color, IMO. You can dial down each individual bulb if they are too bright, and get the perfect insert color. Highly, highly recommend it.
100% agree that frosted bulbs make good sense. Just get those nice domed ones to replace exposed condom bulbs and you're in business
