Methylene blue can be used to dye natural fibres like cotton, wool, and silk in home textile projects. It produces a rich, long-lasting blue hue, making it a popular choice for DIY fashion or home decor. The dye works well with various textile types.

Used as a redox indicator due to its ability to undergo reversible colour changes between its blue oxidised form and colourless reduced form. This makes it an effective tool in demonstrating electron transfer in chemical reactions.
