Yes, make the laundry room a mud room / foyer feel - a happy color on the walls will make a big difference - with three boys you are going to need to have washer dryer but maybe you can stack them a la sherry and john's last house and do a bench next to them with a top shelf and rows of hooks? Deeper color on the wall there - here is a color scheme idea

In the kitchen, definitely invite friends to help you move the frig - that is a no brainer.

What if you paint three walls a pale apple green - bm sweet caroline comes to mind and on the stove wall, what if you paint that all in chalkboard paint? That will make the black and white range kind of the "star" of its wall and combine black and white in the room too but give you a place for making lists and drawing signs. That will give you instant chic and a way to express yourself. Put up quotations about adventure - change is always stressful even when it is good change and you are the captain of the adventure ship. This will cheer you up every day.

The light you have is sweet but I would rather see it in a living room so you can get lots of light fixtures heads - you can always install a dimmer in the kitchen - so you have plenty of light here. Look for one of the ikea multihead aim-them-where-you-want-them fixtures for the kitchen ceiling - good prices there.

Then in the entry / laundry room and living room - I found this lavender gray called pigeon gray at bm - it is a compliment to the apple green tone but it also reads very neutral and soft and sophisticated - you could use the pidgeon gray in the living room and use the deeper lavender tone called wisteria in the entry hall since you will have all the white storage doors and eventually white laundry appliances and possibly a white entry mudroom bench under white shelf with hooks. These colors are not too girly, but they are fresh, pretty with white and can be combined with navy or brown or gray so your main upholstery whatever it is should work fine with them. Yellow/gold accents and natural butcherblock wood will also be terrific with these - nodding to your fixture and covering the water heater - ikea sells butcherblock countertops for a good price - you could cut one length into two elements for some of your goals / use them in the boys room as shelves if you had leftovers so long as someone will cut them for you.

This kitchen is perhaps not the best place for a table for 4 to eat. If you do a corner banquette, a round pedestal table will fit and you can paint a wood handme down straight chairw/ spray paint apple green. That will get 4 of you if boys are not too big and can sit in corner or you might run a butcherblock countertop from the fridge to the corner at window ledge height so you can line up a few bar stools and set lunch up for 3 boys there or have a place to put a buffet or have them help you prepare food / more countertop (a friend having a glass of wine when they are at their dads?) I might look carefully if you would rather put a dining table for homework and all in your living room - divide it in half - table in one half, seating in other half and put this new sweet fixture over your table.

Don't forget when you have your painting party - In your bedroom - get enough wisteria so you can have a lavender bedroom - something pretty while you are embarking on this new adventure. You have to take even better care of you now . . . "put on your own oxygen mask first / sharpen the saw" . . sending my best energy to you.
