Yellow goes with just about any color. But if your sunroom is bight yellow I would pick a softer color for your kitchen. And maybe do a little accenting in the kitchen with the bright yellow in pictures or nick nacks.
Go to your paint store and pick up some of the color samples you think you might like and tape them up on the wall and look at them at different times of the day. Because light changes in a room threw out the day and your colors will look a little different. Then decide which one you like best. I do this when ever I paint and I have changed my mine on some colors I thought I would like because of the way they look in a room at night time. Paint isn't cheap so if you make several trips to the paint store for paint chips it will be worth your effort. It sound like you like bright happy colors so paint it what ever color you would like you are the only one that has to be happy with it.
