I found some information about maroon nail polish and nail art in the search results, but there is no specific information about a "simple" maroon nail art design. Here is what I found:

• Product Details: Two brands of maroon gel nail polish are available on Amazon: GAOY Sheer Maroon Gel Nail Polish and MAYCHAO Gel Nail Polish. The GAOY brand is SGS certified and has lower odor compared to traditional nail polish. The MAYCHAO brand requires an LED light to cure and must be applied with a base and top coat. The Manucurist brand also has a burgundy nail polish called Dark Pansy, which is part of their Green™ range and has opaque coverage and a non-iridescent finish.

• Positive: Maroon is a popular color for nail polish and can be used for a variety of nail art designs. Gel nail polish is a long-lasting option that can be done at home or in a salon.

• Negative: Some nail polishes may contain harmful ingredients such as formaldehyde, toluene, and dibutyl phthalate (DBP). Exposure to UV lamps used to cure gel nail polish can also be a concern.

• Ingredients or Materials: The ingredients in the GAOY brand of maroon gel nail polish are in strict compliance with the FD&C Act and SGS certified. The MAYCHAO brand of maroon gel nail polish requires an LED light to cure and must be applied with a base and top coat. The Manucurist brands Dark Pansy nail polish is part of their Green™ range and has sustainable packaging.
