Rainbows are often associated with owls and dreamcatchers in art. In some cultures, rainbows are said to signify hope, optimism, and luck - while in others they represent a journey of transformation. When combined with an owl and dreamcatcher in artwork, the symbolism is even more powerful. Owls are seen as a symbol of wisdom and understanding, while dreamcatchers tend to be multicolored in design -each color representing a different aspect of life or objective - so having a rainbow colored owl serves as an added layer of power to the piece. This type of art is said to bring good fortune and protection through its intricate designs and bright colors.
