What do purple roses mean? A: Purple roses are sent to an individual to indicate an enchantment or love at first sight. This color is also given to tell the recipient that they are irresistible, but it is not meant to indicate permanence or a seriousness in the relationship.
Purple Color Meanings. Purple has a special, almost sacred place in nature: lavender, orchid, lilac and violet flowers are delicate. Because the color is derived from a mix of a strong warm and strong cool color, it has both warm and cool properties. A purple room can boost a child's imagination or an artist's creativity.
