Why have my emojis turned black and white all of a sudden?

[Android Central Question]

I'm using a 4.1 tablet with a Kii 2 (beta) emoji keyboard, mainly using emojis on Facebook. The change is not in just what I post but also the emojis other people use. It worked fine for a couple of months and then it suddenly changed. I switched back to Google keyboard and tried another colour emoji keyboard but the issue persisted.

it mainly happened because font change, I guess.
search for a setting that allows you to do so.
