For the sake of completeness, it's worth pointing out two things: 1) "Color blindness" isn't a single medical condition. It's half a dozen different conditions, all with different colour distortions, ranging from mild colour spectrum distortion (Protanomaly, Deuteranomaly and Tritanomaly), to complete absence of colour vision (Achromatopsia).
2) The existing design already accounts for this. It's a monochromatic design (all messages in yellow) that uses icons to differentiate between "error", "warning" and "info". The proposed designs are introducing colour, but aren't removing the iconic elements. For me, the only question here is the specific choice of colour. The existing design isn't heavily using colour to communicate significance of a message. Introducing colour will be a UX win for those with colour vision; if we pick a good set of colors, those with a mild colour sensory disorder will still be able to distinguish error types based on colour. However, even if you are completely monochromatic, the icons are still there, so a visual cue exists.
