Pacific Blue is a CertainTeed vinyl siding color: a muted blue-gray with a slate or steel cast. Photos online disagree on how light it is, because blue-grays shift a lot with light and screens. Below is what Pacific Blue really is, which lines it comes in, how it compares with nearby blues, what goes with it, and a tool to try it on a photo of your own house.
One brand, several lines.
Pacific Blue is a CertainTeed color. We did not find it at Alside, Royal, Mastic or Kaycan, so a quote for "Pacific Blue" from another brand is a different color.
CertainTeed lists it in Monogram and in several other lines, such as Cedar Impressions, Restoration Classic, Board & Batten and RISE. Availability changes, so check with your dealer.
The current brochure swatch is a muted, fairly dark slate blue-gray. Some reviewers describe it as light and beachy, others as nearly gray. In shade it reads grayer; in full sun it reads bluer.
If Pacific Blue is close but not quite right.
Alside Mystic Blue is a softer, lighter gray-blue.
Alside Harbor Blue and Midnight Blue are deeper, with Midnight close to navy.
Royal Indigo and Gentek Coastal Blue are often named among the best blue siding colors.
Pairings for a blue-gray house.
Crisp white trim is the classic choice and brings out the blue.
A red or yellow door gives a coastal look. Natural wood also works.
Charcoal or black shingles suit it best.
Gray stone at the base keeps the cool tone.
A picture helps you choose a direction. These checks help you choose the actual siding.
Siding looks lighter in full sun and darker in shade, and a small chip looks darker than a whole wall. Hold a sample against your house at different times of day before you order.
A Clay or a Sage from one brand is not the same colour as one with the same name from another brand. Always say the brand, the product line and the colour name together.
Within one brand, each siding line (for example a budget line and a premium line) has its own colour list. A colour you like may only exist in one line.
Dark vinyl colours absorb more heat. Most brands make their deep colours in heat-resistant lines; ask your installer before choosing a very dark shade.
Many homeowner associations approve exterior colours. Ask before you order, and bring the picture with you.
Save your before and after picture and take it to two or three local siding installers when you ask for quotes. Tell each one the brand, the line and the colour name you want.
Ask each installer to bring a sample of Pacific Blue and to confirm it is stocked in your area. A picture of your own house makes it easy for them to see what you mean.
The tool draws an approximation of each colour from a description of its tone. It is not the manufacturer's swatch, and the siding profile is a general lap, shake or board-and-batten look, not a specific product.
It is a preview, not a quote or a survey. It does not measure your walls or give prices.
Trim, shutters and the roof are kept as photographed. If you plan to change them too, use the house painter or roof tools afterwards.

CertainTeed. We did not find a Pacific Blue at Alside, Royal, Mastic or Kaycan.
It is a muted blue-gray. The current CertainTeed swatch is fairly dark and slate-like; in bright sun it can look lighter and bluer.
White trim is the classic pairing. A red or yellow front door adds a coastal touch.
Charcoal or black shingles.
Monogram, and lines such as Cedar Impressions, Restoration Classic, Board & Batten and RISE. Check current availability with a dealer.
The picture is an approximation. Blue-grays shift with light, so look at a physical sample outside before you order.
