1) Blue: 418 - Dolphin Blue with Charcoal and Dark Blue.
2) Yellow: 618 - Canary Yellow with Plum and W. Day Green.
Note: I'm aware that the 618 pattern is also used on the red chip. But at least for "standard" colors these two chips won't be at the table together: For Vegas colors they're too far apart (5 vs 1000). I don't know what red is used for in Cali but a .25/1/5/20/100 cash set progression shouldn't need a red one.
And here's how they look like.
