My brand new roof is wavy and hasn't settled down even with 70 degree days and also appears patchy (different colors) only in the sunshine. In the shade it looks fine.

Is it poor installation? or old shingle inventory? I have two photos; if you need to see them, let me know.

I'd be insterested in seeing photos.

One big reason for "wavy" or "humpy" shingles is having shingled over "buckled" or "rippled" felt.

Felt can be buckled or rippled from moisture in the felt itself, right off the shelf, or from rain or snow, etc. Even though the felt may appear totally dry, it can retain moisture, untill it's had a chance to dry out, depending on sun, hunidity, etc. Where I work it can dry out, and shrink perfectly flat in as little as an hour or two. In humid conditions, it might take several days. The felt buckling CAN be "worked out" fairly flat when shingling through the use of extra nailing. But once it's been installed that way: shingled over, it probably will stay that way for the life of the roof. I know of one job I saw guys doing, in the middle of actual snowfall, which still looks that way 10 years later.

There's a possibility that one MIGHT go back up there, and carefully lifting some of those shingles, install extra nails here and there to suck it back down, but they probably won't ever look like they could have if they were installed over a flat surface.

Sorry...the second part of your question: different coloring....

You MAY have a particular color blend which will "look" different in differing light conditions, or you may have some shingles which had the color granules "misaplied" by the manufacturing equipment used in making them. I do run accross "mis-colored" shingles on occasion. If that's the case here, they should have been noticed, and set aside without using them. But, in fairness to the roofer, shingles can also look different when facing them from a distance of 2-3 feet rather than from the ground. So, it could have been easy to miss the off-color if they weren't "off" that much looking at them close up.

One last possibility, though not as likely {do not be unecessarily alarmed}, is that the shingles could be #2 product. #2 product is not legal to use in most places. It consists of shingles {in this case}, which do not meet the standards set forth by the manufacturer. Even then, it doesn't mean there's anything wrong with the shingle other than the off-coloring.
