I use IDEA, Eclipse, VS, etc on an e-ink. Use the light-theme that comes with your IDE (not the Dracula theme). You will see the colors as different shades of gray (not just b&w) - it's fine, one gets used too. And color e-ink exists just still too expensive - there were rumours that the next Kindle after v3 gets a color e-ink (2010), but Amazon shifted the focus to Kindle Fire. The technology is there, just the volume is too low, so color e-ink are still expensive.
