PMS 688 C is a standardized color from the Pantone PMS collection, used widely in applications demanding visual consistency, such as branding, displays, and prototype work. The color presents a restrained, cool-leaning purple with a medium-to-deep value. PMS 688 C communicates controlled, technical, understated, and sophisticated qualities in use.
- PMS 688 C appears as a medium-dark hue; its LRV is 22.93, placing it in the lower third of the lightness range.
- The color exhibits a cool temperature, reflecting a purple oriented near magenta on the hue wheel.
- PMS 688 C demonstrates moderate to low saturation for a purple, imparting a subdued appearance rather than a vivid one.
- The undertone is clearly cool, with hints of blue-lavender visible, especially in indirect light.
- This color is somewhat sensitive to finish; higher-gloss finishes may intensify its depth and apparent chroma, while matte finishes impart a more neutral, muted effect.
PMS 688 C works well in environments requiring a distinct yet unobtrusive purple that avoids high vibrancy. It performs reliably on both display-grade and architectural surfaces where a controlled, brand-centric appearance is important. For best results, always evaluate samples in the actual lighting and finish intended for the application. This color may appear darker and cooler in northern or shadowed lighting and can exhibit noticeable differences between gloss and matte substrates. Surface preparation should ensure a uniform base, as deeper purples may show subtle streaking unless fully covered.

When using PMS 688 C for prototypes or concept models, select a paint format that matches your project requirements, such as spray paint for large or irregular surfaces or paint pens for detail work. It is important to apply PMS 688 C to test pieces representing your final materials and lighting conditions before proceeding to production. Evaluating samples in the intended context helps ensure the color appearance aligns with brand standards and avoids costly changes after ordering in bulk.
PMS 688 C matched paints are custom made to order and cannot usually be returned or exchanged. It is critical to carefully select the correct product type, finish, and quantity before ordering. If you are unsure, ordering a small sample or test quantity first is recommended. This approach helps ensure the final product meets your expectations and reduces risk of incorrect selections that are difficult to fix once production begins.
PMS 688 C can appear differently depending on the substrate or material due to factors like surface texture, absorption, and reflectivity. For example, the color may look deeper and glossier on metal compared to a matte plastic. To ensure the desired color outcome, test PMS 688 C on the actual materials used in your final application and view samples under intended lighting. This step helps prevent unexpected appearance shifts between prototype, display, and final components.
PMS 688 C, as a cooler and moderately saturated purple, may require multiple coats to achieve full, even coverage, especially over lighter or uneven bases. For best results, consider applying a uniform primer or undercoat shade that supports the hue, such as a gray or a color close to the mid-value of PMS 688 C. Testing your coverage process on a sample surface is advised, as this color may show subtle streaking or unevenness unless fully covered.
Unfortunately, no.
Some manufacturers specify Pantone colors as touch up for their products, but Pantone does not work well as a proxy for a touch-up solution (for a litany of reasons such as it doesn't include sheen and Pantone color tolerances are not tight enough for touch up). When we match Pantone colors we are matching to a swatch in a Pantone book - not to your product.
The only way we can provide a touch-up solution for your product is for you send us a part. We would use the part to create a touch-up grade match. Unfortunately, there isn't an effective way to 'spec' the color well enough to produce a touch up without the part.

To make spray paint matched to Pantone PMS 688 C. MyPerfectColor uses an acrylic enamel which is a fast-drying durable coating suitable for interior or exterior use. MyPerfectColor custom spray paint enables you to conveniently achieve a professional spray-smooth finish in any color in any sheen. It sticks well to most surfaces including metal, plastics, powder-coatings, cabinets and primed or previously painted wood.
The 11oz spray will cover about 20 square feet per coat. Keep in mind that it is difficult to gauge how much spray you'll need as it is highly dependent on how it is applied. It is better to have too much than run short.
While MyPerfectColor can provide PMS 688 C 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 company's color collection, especially for a color collection like Pantone which is designed for bright colors and inks.
