I'm sorry you feel like you hate the project. I've been in that position myself. I also plowed ahead and completed the project and it doesn't necessarily improve. If you do get your daughter involved in selecting the colors she will probably love it even though even though it may not be your favorite. But if her enjoyment is your goal, you will be successful.
After completing my quilt I was not too happy with color selection, I made another quilt from my stash of favorite quilts. I think it is attractive and let me move on. So that's my suggestion. Get the recipient involved so you can detach then do a follow-up therapy quilt for you.
For what it's worth, I like the pattern you are making. The color choices determine the mood. From the two examples of items in your daughter's home they are subtle contemporary and I think the muted colors will be the best fit.
Please don't send it to the trash!!!
