Basically what Fish said. Red and Magenta are too close in hue to be easily readable. And considering you're working at max saturation (which can be a risky business, but let's not go there), it's all looking a bit eye bleeding.

Even if you did the lazy thing and switched the magenta for blue (or green!), the readability would go way up. Won't fix the eye-bleed, though.
