Match of Sherwin Williams™ SW1840 Rich Amethyst *

Custom-matched orders should be chosen carefully because they are made to your selected brand color reference, product type, sheen, and quantity. If any of those details are wrong, the result may not fit your project.

For SW1840 Rich Amethyst, confirm the exact MyPerfectColor product format and sheen before ordering, since custom color matches are not returnable or refundable.

Coverage depends on the surface size, texture, hiding power, application method, and how many coats are needed. For SW1840 Rich Amethyst, plan based on the actual item and whether the surface is smooth or porous.

A typical can of spray paint covers about 20 square feet with one coat. Other MyPerfectColor paints typically cover between 400 and 600 square feet, but real coverage can be lower or higher depending on the job.

The SDS is tied to the specific MyPerfectColor product or chemistry, not to the SW1840 Rich Amethyst color name by itself. You should check the SDS for the exact product format you are ordering.

MyPerfectColor Safety Data Sheets are available on the Safety Data Sheets page for the product. If you need the SDS before ordering, review that page for the exact paint type.

Yes, but plastics vary widely, so testing on the actual material is important before you paint the full part. A match of Sherwin Williams SW1840 Rich Amethyst can be ordered in MyPerfectColor spray paint for many projects, but the surface may need different prep depending on the plastic.

MyPerfectColor spray paint sticks well to most plastics, and using the MyPerfectColor primer can improve adhesion. If the part is critical, test the exact plastic first so you can confirm adhesion and appearance.

Even when the color match is correct, SW1840 Rich Amethyst can read differently after application because lighting, placement, sheen, and nearby surfaces all affect how the finish looks.

This is especially important if the finished item will sit next to an existing painted surface or be viewed in changing light. The color target stays the same, but the applied result can appear different on the final object.

Please note that if your material is not new then the paint may not work for touch up as your material has aged and is likely different than it was when new.

If you need a touch up application, send us a part and we can create a touch up solution precisely matching the current color and sheen of your specific materials.

While MyPerfectColor can provide paint matched to the Sherwin Williams SW1840 Rich Amethyst, we don't provide any crossover information because this is a subjective determination. 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, so determining which color is the best approximation is a judgement call.

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