Confirming the above - dyed pellets definitely color bird poop - problem with that, it can be difficult to identify dropping changes that indicate health problems. I don't like them because of artificial coloring. A pellet based diet is only PART of a healthy diet, so adding fresh (organic if possible) veggies and fruits are essential for health. Many parrots will take to broccoli, sugar snap peas in the shell, green beans, peas, carrots, sweet red peppers and the like. Cherries, pomegranate seeds, papaya, oranges, apples, beans, brown rice, whole shell nuts (in moderation), sweet potatoes and grapes are also ideal for nutrition. I have been adapting my rescue Cockatoo from a strictly seed mix diet (horrid for them!) to fresh food for the last month. Whatever you introduce, eat FIRST in front of your parrot (insert yummy sounds here!), and they are more likely to try the offering. Yes, lots of stuff hits the floor, but I keep adding them to her dish - eventually she is recognizing fresh offerings as food, or gets used to the taste as it's flavor touches other stuff in the bowl she DOES like
Seeds are high in fat - some parrots need more than others, so I'd look for Quaker Parrot sites that address proper diet balance. Some species (Cockatoos) can develop weight/reproductive issues from too much fat in the diet. My guys get bits of hard boiled egg, cooked chicken, even tofu! Diet conversion is a slow process, so I suggest to start slowing mixing in new pellets (Zupreem organic and Harrisons are great) with current feed, then increase new ratio a bit at a time. Some will take to new organic pellets more quickly by mixing with a little apple juice - they are not as sweet as colored pellets so expect some time for adjustment. Congrats on your new baby!
