These fluorescents are opaque with a smooth and consistent texture, however, they are not lightfast. If left in direct sunlight for 30 days, pieces painted with fluorescent watercolor will fade by 50%. This can be reduced by coating finished pieces in a UV protective varnish and/or keeping them out of direct sunlight.
