The Light Blue Dye item texture still uses the old outdated color from prior to the 1.12 update to colors and dyes.

What I expected to see: Light Blue Dye item would have identical color to Light Blue Wool block, and Light Blue Banner, Light Blue Shulker Box, and Light Blue Concrete.

What is seen instead: Light Blue Dye item instead is using the old color from 1.11, so it is too far off from the current color for Light Blue Wool, Light Blue Banner, etc.

Most other colors stayed similar so other dyes aren't affected. Howeber, Light Blue blocks changed color signficantly in 1.12, and so Light Blue Dye ends up being too far off and now not the right color as the matching block set.

This is a copy of MC-264444 , but specific to Light Blue Dye item. The same attachments found in MC-264444 apply here.

Note the Light Blue blocks in both images. 1.11.2 on the top, 1.20.1 at the bottom. Light Blue Dye for clarity in 1.20.

Here's Light Blue Dye show in 1.11, and current version. The colors used to match, but now it doesn't in 1.20.
