Image needs new colors for color blind

[edit]

While the image is a good example of a spiral, conical helix and helix, it needs different colors. For someone like me who is red/green colorblind it is tough to easily distinguish the the three shapes. The image should be high contrast, have a black background and the shapes should be red, yellow and blue (this also helps blue/green colorblind). The image should also be an SVG instead of a fixed resolution PNG.
