Hey Preerj,

I am sorry that delay of this reply,

I've tried in my locally, it seems work fine, you can take a look of my attached screenshot below.

Perhaps you can provide us with your Joomla backend and FTP access so we can help you check on this?

Unfortunately that was not possible to insert color code in that field at this point of time. But it would be best if you can submit a feature request regarding this in our voice page -> http://stackideas.com/voices/easyblog, so everyone else could vote for it, the more people request on this, and we will priority consider it.
