Do something like: data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' http://www.w3.org/2000/svg' viewBox='0 0 1 1' /> And don't bother with the color

Do something like: data:image/svg+xml,<svg xmlns='http://www.w3.org/2000/svg' http://www.w3.org/2000/svg' viewBox='0 0 1 1' /> And don't bother with the color there, just set a background-color on all IMG elements in CSS, the svg will be transparent.
