Here is the actual color palette.

I would move the sink under the window and scoot the dishwasher closer to the fridge. If you take out the corner base cabinet, it will be easier to use that counter space as your main cooking/prep area.

The island is nice for seating and extra prep/baking space! Nice color palette, too :)

You don't have any wiggle room. It's going to be tough to just cover the bases. Keep the upper and lower corner cabinets square - angled cabinets and counters eat up floor space big time. Definitely get the sink out of the corner and put it under the window. I wouldn't angle the counter and cabinet to the left of the stove; leave it square, because that's precious counter space. Let the wall cabinets on the stove wall run straight into the corner - you'll get a much more open feel around the sink and window. Think about a heavy duty stainless steel prep table on casters instead of a fixed island for more flexibility.

I agree with putting the sink under the window and getting rid of the angled corner cabinet. Instead, go with a squared off cabinet in the corner and get one of these Hafele blind corner cabinet pull out shelves. When you open the cabinet door, one part of the unit pulls out and that motion pulls forward the portion that was recessed into the corner so that you can easily get at the back items. no more head first climbing into the blind corner cabinet. It's not a cheap unit, but it's super durable. We have one and it's the best feature in our kitchen.
