The native Android e-mail client gives you the ability to see all the e-mail in your different accounts on one screen. The operating system identifies which account the e-mail is in by tagging the e-mail with a colored line at the upper right side of the of the e-mail. The feature allows you to visually screen your combined e-mail In Box and look for e-mail from a certain account. The problem is that Android may assign color codes to your accounts that are hard to tell apart. Which leads to the question in this post: How do you change the e-mail account color in Android Jelly Bean? This approach should also apply to other versions of Android too.
The first place I looked to answer this question was the e-mail preferences in Jelly Bean. Seems logical, right? But, even with all its customization options, Jelly Bean does not allow you to change the color assigned to an e-mail account. Next, off to the Google Play store to find an app that allowed you to select the colors you want to use to identify your different accounts. There is an app like that to change the color for different Google Calendar accounts. I was surprised to find no app in the Google Play store that did this.
So, off to the forums. Digging into some Android forums, I found that this question had been asked by several people. The best answer is that Android assigns account color codes in a set pattern as the accounts are set up on your device. The only way to change the color assigned to an account is to delete the account and add it again. One person went to the trouble of identifying the color sequence:
Green, Dark Light
Green, Bright Light
Green, Med Light
Green, Medium Dark
Purple, Dusty Light
Blue, Dusty Light
Purple/Blue, Dusty Light
The cycle then repeats itself. This was posted by xchief6 on Droidforums: http://www.droidforums.net/forum/android-tech-support/3386-color-email-account.html. I admire patience it took to work this out. Thanks to Albert J. Finniwinkle for giving me the cite.
The color change process is not convenient, but I have tested it and it works. Has anyone found a better way to change the e-mail account colors? Leave a comment and let us know.
