A match of Ralph Lauren RL1904 Casino Blue reads as a light, cool blue with a soft cyan cast and a muted, slightly gray finish. It is not a saturated primary blue; the color feels quieter and somewhat softened by its low chroma.

MyPerfectColor custom spray paint matched to the selected brand color can be used on vents, switch plates, speaker grilles, camera housings, shelf brackets, mailboxes, and similar small parts where a cool blue needs to be carried across metal, plastic, wood, or previously coated surfaces after proper prep. It also suits removable fixtures and accessories that need a consistent color on compact, sprayable surfaces.

Because the color is fairly light, thin coverage can still allow dark or uneven substrates to show through, especially on patchy plastic or worn metal. Finish, texture, and film build can change the read of the color, with smooth surfaces usually showing the blue more clearly and rougher surfaces softening it. If you are coating a single part beside an older painted surface, differences in sheen and surface wear can be noticeable.

About Ralph Lauren Paint Colors

MyPerfectColor matches all Ralph Lauren colors in spray paint, touch-up paint, pints, gallons, and more.

For many years, Ralph Lauren offered paint and color collections through partnerships with paint manufacturers and sold these through various home centers. A few years ago, Ralph Lauren decided to stop selling paint and as a result, it is no longer available to purchase, and thus for many people, these are simply discontinued paint colors.

But you are not out of luck. You can find Ralph Lauren RL1904 Casino Blue at MyPerfectColor, of course! MyPerfectColor uses its expert capabilities to recreate the original Ralph Lauren color by matching the original Ralph Lauren color books and swatches. MyPerfectColor does not use Ralph Lauren paint as it is no longer available. MyPerfectColor matches Ralph Lauren RL1904 Casino Blue based on Ralph Lauren's color publications. The colors shown on this website are computer video simulations of the Ralph Lauren Color and may not match Ralph Lauren Color standards. Refer to Ralph Lauren Publications to obtain the accurate color.

Please know that MyPerfectColor is matching the original Ralph Lauren RL1904 Casino Blue. If you intend to touch up paint that has been on your walls for many years, know that your color has undoubtedly changed from the original due to exposure to light and age and the new paint may not match.

MyPerfectColor does not offer matches of any Ralph Lauren Specialty Finishes such as the Suede, River Rock, or Metallic finishes.

Frequently Asked Questions About Match of Ralph Lauren™ RL1904 Casino Blue *

How long does MyPerfectColor RL1904 Casino Blue spray paint take to dry, recoat, and handle between coats?

Dry-to-touch, recoat, and full cure are different stages, so do not treat them as the same milestone.

How should I confirm RL1904 Casino Blue before ordering a MyPerfectColor match?

Confirm RL1904 Casino Blue from a physical swatch or a known existing painted sample from the original Ralph Lauren reference, not from a screen image alone.

How do I convert Ralph Lauren RL1904 Casino Blue to a different company?

While we can provide Ralph Lauren RL1904 Casino Blue in paint, we don't provide any crossover information. We've found that every paint company offers its own unique selection of colors and rarely does a color have an exact equivalent in another brand.

However, under the color image on a color page there is a link that says "Explore Colors". Clicking this link displays colors with similar values and you can look for any colors from the brand you want.

Keep in mind that this just shows similar colors based on the color values we have stored in our database. It doesn't mean it is the same or give any approximation about how close the color is. You can play around with the Hue, Lightness and Chroma sliders to expand the selection.
