Colored glass is not in creative inventory

I saw the new glass panes, and wanted to see if there was colored glass.

What i expected to happen:
Colored glass would be in creative menu/inventory

What really happened:
Colored glass was not there (panes were, but in decorative).

How to:
Press "E" to open up inventory. Top left tab in the creative menu.

As a side note, the crafting recipe for colored glass works fine. But the item is not in the creative inventory
