DEAR user interface - Colorblindness accessibility

Just a usability note for consideration:

The quote/pick/ship/invoice/pay icons for these steps use different colors to indicate the status of each step, but this functionality is not effective for a colorblind person. Perhaps consider using a border or inverted color/background for one of the states? Else at least use bolder colors, because colorblindness picks up shades better than actual color. Admittedly the tooltips are there, but they are not practical for scanning the list by eye.
