# Annoying Glass
Annoying Glass adds the Chromatic Prism, a reusable tool for choosing the color of clear glass during crafting.
## Features
- Shift-right-click the prism to open a 4×4 color picker with a preview of each stained-glass block.
- Click a color to save it on the prism; the selected color is retained when crafting.
- Combine the prism with one clear glass block or one clear glass pane to receive the matching vanilla stained-glass block or pane.
- The prism is non-stackable and lasts for 16 conversions.
- The prism's item texture animates through rainbow colors.
- No dyes or Polymorph are required.
- Modded clear glass blocks and panes are supported when their items are included in `c:glass_blocks/colorless` or `c:glass_panes/colorless`.
