You may want to consider that the day light up north is different from Florida. The deeper colors up north are amazing there and the somewhat more vibrant colors in Florida are wonderful here. I bought a house with a crocodile green living room. Up north the same color would look sea-sick green. Here I didn’t change it because it gives the feeling of a sun lit forest. I actually have grown to love it.

(Just a couple of possible tips adding to comments already posted by "Velvet" & others.)
Because lighting is different in different areas of the country, in different homes, and in different areas of the same home at different times of the day, if you are able (unless by now you have found the color you decidedly prefer above all others), it may be worth your time to do this in the actual home you plan to paint:

Buy small jar samples of your potential color choices (Sherwin-Williams does not offer them, but at Home Depot you can get them for Sherwin-Williams and other paints for apx. $4). If you cannot get the samples in the paint finish you plan to use (flat/satin etc.) then buy quarts in the paint type you want even tho you'll be wasting a few $. Example, satin can appear slightly lighter than flat due to being more light-reflective.

Buy a corresponding number of white foam-filled poster boards at Dollar Store ($1.25) or Walmart & paint each board with one of the colors and paint types under consideration (boards are easy to use because they are firm & stand up easily). Dollar store also has cheap wide brushes so you can even buy a brush for each color & discard afterwards so no mess to clean, and if you don't have a drop cloth, buy one or more at $ store or invest in a reusable canvas one.

Paint at least 2 coats or the colors will not be accurate.

Place the boards against the walls in the various locations to be painted and compare them AT VARIOUS TIMES OF THE DAY (due to variations in lighting).

Interestingly, if you are having difficulty choosing between colors during this process, there will probably be at least one time of day when your order of preference will be obvious.

This might not what you were lookin for. It is not blue. We went to shrwinnWilliams and picked the color cucumber for our family room area. For the hallway and kitchen we picked a soft yellow

HUH? Any paint color looks different to different people. You can purchase small samples of paint. You can also purchase or cut squares of sheetrock so as to make large samples of the color and then try them out in your lighting. The type of lighting you have also effects the way a color will look.

As mentioned by others here, buying sample-size paint and using poster board or 2x2 pieces of drywall to make your samples can be money well spent. The size of the samples you make and move around at different times of day will save you from an expensive mistake.

Another approach to think about is to find a picture with shades of blue and of a size to be a focal point in your room and work backwards from those blues.

art.com has a seemingly overwhelming choice of inexpensive prints that you can have mounted and framed. But you can filter by subject, style, and, if I am remembering correctly — color. (It’s been a while since I bought from them, but I have in the past and with success.) Also, you can look around locally for a picture you like. I have found stuff at Goodwill, including a signed print.

Have fun feathering your new nest.
