Watercolorist → It is formed from "water" (from Old English "wæter", meaning liquid that falls as rain or flows in rivers) and "color" (from Latin "color", meaning hue or tint) and "-ist" (meaning one who practices or is concerned with). A watercolorist is someone who practices the art of painting with water-based colors.
Think of someone who uses 'water' as their medium and 'color' to create art — that's what a watercolorist does.
