Chili Pepper 180B-7 is an appropriately named color- it is a HOT red. Please note that a tinted primer is recommended for this color and it will require multiple coats. Not having more details on your project, I will give you a couple of suggestions for pairing Chili Pepper 180B-7 with blue. I do assume in all of the recommendations that you are using Chili Pepper 180B-7 as an accent color so I have not recommended blues that are as deep and vibrant as Chili Pepper.
A very popular trend right now is hot red and soft turquoise. It is big in everything from home furnishings, to wedding colors and the combination even made quite an appearance in holiday decor this past December. To play to the blue influence, choose a soft turquoise that is more blue than green, such as Harmonious UL220-6 or Agave UL220-18. The soft, cool turquoise will allow Chili Pepper 180B-7 to pop since it will not be competing for attention in the room. This is a very modern take on the classic blue / red combination.
A hot red such as Chili Pepper 180B-7 is very strong and when it is paired with a blue, it easily takes on a patriotic feel. If this is the look you desire, Forever Denim UL230-5 is a solid and muted blue or Simply Blue UL240-15 is an appropriate sky-blue. The combination does have patriotic undertones without becoming a literal translation of the American Flag colors.
If you are trying to pair a blue with Chili Pepper without the patriotic feel, I recommend that you look at a blue that is very muted or grayed so that the blue is an undertone. Coastal Vista UL230-6 feels grayed until you put it next to Chili Pepper and then the blue undertones start to emerge. I also like Polar Drift UL230-11 for this same reason if you are looking for a very light and subtle blue.
