If you want to identify blocks in their shape and color, consider using this resource pack for the mind-blowing textures.
Using these textures is way more fun than using the default ones. The Faithless texture pack is not only useful for those who are visually impaired, but also for those who have a hard time discerning the difference in colors. Its color combinations benefit visually-impaired players by allowing them to tell the difference between the colors of the blocks and textures in the game. The Faithless resource pack does not focus on either connected textures or dull realistic hues.
Players who have a regular vision may find these color hues a bit odd or too colorful.
