coloured emojis for samsung s3

[roxi9791]

Hi I'm. I'm new to this page. But I was wondering if someone can help me. I can't seem to get coloured emoji's on my Galaxy s3. I've tried a few apps Kii keyboard and android keyboard, they both have the colour emojis on the keyboard. But as soon as I post to Facebook/twitter etc the turn black and white! My android system is 4.3. Thanks in advance to anyone that can help 😄
