Painting white flowers can be challenging in watercolor because instead of using white paint, you must save the white paper. It requires a little bit of pre-planning and a light touch when applying the shadows on the petals. But, you can also have fun using all sorts of colors that are reflected from the background on to the white flower itself.
It sounds like a contradiction, but limiting yourself in your artistic practice can actually make you more creative. Too many choices of colors can be overwhelming. Limiting your colors can help you focus on the shapes, values and composition, forcing you to make stronger decisions. It can also stop you from overthinking and frees you up to be more free and bold.
Butterflies symbolize transformation, rebirth and hope. They represent the soul's journey and spiritual evolution and across different cultures can also signify freedome joy, love and lightness.
