This is a photograph by Katya Horner entitled "butterfly in scarlet." It is available at her shop: slightclutter on etsy. This listing can be found here.
Viewing this piece, I was struck by its color, pattern and subject. Color is one of the main components that makes the piece visually appealing; particularly the saturation and contrast of color. The eye is drawn to the contrasting tones of the butterfly: the lightness and saturation of the yellow, which contrasts with the darkness and purple tinge of the black. The eye is also drawn to the butterfly for the pattern of the color of its wings and body. The eye then moves through this visual of color and pattern to the super saturated tones of the background of the image: where magenta mingles with hues of purple, puce, and sienna. And these background colors appear softer focus, with less articulation, which further emphasizes the pattern of the butterfly as the focus of the piece. It's a contrast between the intricate pattern and contrast of the butterfly juxtaposed against the soft focus and saturated color melding of the background that makes this piece visually appealing.
I encourage you to check out the rest of the pieces available at slightclutter on etsy.
