Match of Martha Stewart™ C21 Hydrangea Blue *

Yes, MyPerfectColor can supply a custom-matched paint for C21 Hydrangea Blue in spray format for many plastic items, but plastics vary a lot. Before ordering, test on the actual plastic part if possible. For better adhesion on difficult or low-energy plastics, use the MyPerfectColor primer for Acrylic Enamel before applying the color coat. That helps reduce the risk of peeling or poor bond on parts like covers, trim pieces, housings, or accessories.

For metal or a previously painted surface, clean the part first to remove dirt, grease, and other contamination. If the surface is glossy, lightly scuff it so the new coating can bond better. Check for rust, loose paint, or failing coating and remove anything unstable before painting. The condition of the old surface, along with its gloss and texture, can affect how the matched C21 Hydrangea Blue finish looks, so a test spray on a small area is a practical way to reduce risk.

Confirm C21 Hydrangea Blue from a physical swatch, a known existing painted item, or another trusted original brand reference rather than relying on a screen alone. MyPerfectColor makes a match of C21 Hydrangea Blue in its own paint, so the most important step is verifying that C21 Hydrangea Blue is the target color you want before placing the order. That matters most when you are matching an existing part or coordinating with a surface that is already painted.

Choose the sheen based on how the item will be used and how much surface imperfection you want to show. A flatter finish can hide texture better, while a glossier finish is more reflective and usually easier to clean. The same C21 Hydrangea Blue color can look different as sheen changes, so the finish is part of the ordering decision, not just the color name. If you need the new coating to sit near an existing painted surface, try to match the sheen as closely as practical.

The SDS is tied to the specific MyPerfectColor product and chemistry, not to the C21 Hydrangea Blue name by itself. If you need safety information, check the MyPerfectColor Safety Data Sheets page for the exact product format you plan to order. If you are comparing spray paint, another coating type, or a different finish, make sure you review the SDS for that specific item.

MyPerfectColor has an original sample of the Martha Stewart C21 Hydrangea Blue in its color archive. This enables us to make paint and verify that it matches the original.

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. Learn more about our color matching accuracy. 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 Martha Stewart C21 Hydrangea Blue, 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.
