I have not used the HGTV color collections, but have used the DEVINE COLOR Discovery Cards and their Color Sheets.
I painted my home a few years ago and since then have been asked by dozens of friends to help them with picking whole home pallets. I now own all the Devine Color Sheets plus a collection of 100 BM painted color sheets. Planning on starting a business helping people pick a whole home pallet.
You may need to alter my method a little since you don't have every color at your fingertips, but you can use the discovery cards or the tools from HGTV.
Here is the plan:
Pick up samples from home depot or lowes that match all the floors counters cabinets -hardscape items that are not going to change if you don't already have portable samples.
Spread out a large white sheet in a sunny room or sometimes outside - natural daylight really helps you see subtle differences in color.
Lay out the hardscape items across the sheet in the same flow as you would have walking through the house.
Add the other colors that are going to stay. (couch, furniture, bedding).
At this point pick a neutral. What works best with everything you have that is going to stay in your home. This is the most important piece of the puzzle. Every neutral has undertones. Grays and tans both have undertones that have to work with the hardscape items in your home. (This is what causes the pink wall syndrome - looked neutral, but turned pink when I painted it on the walls.) (My sister's white has a distinct green tone to it. She couldn't see this with the little 1x1 paper sample the builders gave her.)
Now it is time to have fun! Bring in the the colors that make your heart sing. If you look in your closet and around your home and at the art that you have purchased you will find that you already own the colors you love. Which of these colors should be added to each room. Think about this part of the process kind of like a mix and match wardrobe. . . Does the color you love in the kitchen work with the family room that you see when your in the kitchen. Do the colors flow from room to room. (The discovery cards will be sufficient to pick out the colors that you love, but not sufficient for the final selection.) Each room will have the 4 walls a ceiling floor and trim, furnishings and accents.
Think about each room and what feeling you want in that room. Do you want it to feel peaceful and relaxing or brighter and more energetic. Pick the paint colors and the accent colors - play with the colors in each room until you come up with your personal home pallet.
With a 3000 sq ft home I would expect about 7 colors, a neutral and a white.
At this time, you want to order or make 8 1/2 x 11 painted sheets of heavy stock paper of each of the paint colors (including the neutral and white).
Paper samples do not truly represent the color and no one can pick undertones and really see the colors from a tiny sample.
Lay these out on your white sheet - do you need to adjust any of the colors - is the blue just a little too purple or the red a bit too orange?
Make new painted sheets for your almost final selection.
The last step is to place these colors in the rooms where they will go. Look at them in the morning and afternoon and evening. If it is a dark room the colors will go gray and you may have to increase the intensity.
Make new sheets with any final adjustments.
This is your final whole home pallet. I suggest keeping the sheets in a notebook to take with you when you go shopping. You will never again buy something and bring it home only to find that it doesn't quite work with the colors in your home.
