I was able to get contact with the color lab from Behr and they were able to give me approximate colors in the Behr core palette that match with the Pantone colors on the UI Creative service website. For the orange, P180-6 Pimento was suggested and for the blue M530-7 Elegant Navy. I am looking at the color swatches now and they do look pretty good for an approximation. Being in the coatings industry, I would suggest you buy a couple samples of the colors first to make sure you like them and if you choose these colors, use a tinted primer underneath the orange color of Pimento. I know all of the gallons say paint and primer, but there is not actual primer in paint, that is for marketing. They carry primer attributes only, and certain oranges, yellow, and reds can be difficult to paint with.
Again, it is extremely difficult to match Pantone colors and virtually impossible to do under the color match machine at paint stores. Should you bring something in to color match, fabrics will not work as too much light can shine through the fabric and throw the color off. You need something at least the size of a quarter, solid piece, and the less shiny the better.
