Banners

The color for the banners aren't showing up on Minecraft for me, and the only color I see on banners are white.

Can you make the colors on the banners appear please?
Can you add colors for me to see?

I can't see the colors
When I go to see banners I only see white on Singleplayer and Multiplayer servers.

1.Fix the bug
2.Make sure other people don't have the problem
3. Add the color to the banners
