The blue glass absorbs all colors of light EXCEPT Blue, which passes through and to your eyes.

Stentors have been stained with a bright blue dye to make them easier to find under a microscope. This staining enhances their visibility against the background, allowing for more straightforward observation and study. The blue color contrasts well with their natural environment, making them stand out significantly.
Democrats are blue.

The toilet seat may be stained blue due to the presence of certain cleaning products or chemicals that have been used in the bathroom. Some toilet bowl cleaners contain blue dye or chemicals that can transfer onto the seat, causing it to appear stained blue.
methylene blue
Blue. The infamous stained blue dress.
Starches turn blue-black when stained with iodine (which usually stains things a reddish-brown or amber color).Iodine turns blue black when starch is present
I have the same issue :( Any luck?
The organisms are stained with fluorochromes, and when exposed to ultraviolet, violet, or blue light they become a bright image resulting from the fluorescent light emitted by them. This exposes the capsule.
There are a few. There's blue stained glass, Lapis, Blue Wool, Cyan Wool, blue hardened clay, and diamond.
Methylene blue can be used to stain E. coli so you can look at it under a microscope. As an alternative, you could try gram staining.

Gram positive cells take up the crystal violet, which is then fixed in the cell with the iodine mordant. This forms a crystal-violet iodine complex which remains in the cell even after decolorizing. It is thought that this happens because the cell walls of gram positive organisms include a thick layer of protein-sugar complexes called peptidoglycans. This layer makes up 60-90% of the gram positive cell wall. Decolorizing the cell causes this thick cell wall to dehydrate and shrink, which closes the pores in the cell wall and prevents the stain from exiting the cell. At the end of the gram staining procedure, gram positive cells will be stained a purplish-blue color. Gram negative cells also take up crystal violet, and the iodine forms a crystal violet-iodine complex in the cells as it did in the gram positive cells. However, the cell walls of gram negative organisms do not retain this complex when decolorized. Peptidoglycans are present in the cell walls of gram negative organisms, but they only comprise 10-20% of the cell wall. Gram negative cells also have an outer layer which gram positive organisms do not have; this layer is made up of lipids, polysaccharides, and proteins. Exposing gram negative cells to the decolorizer dissolves the lipids in the cell walls, which allows the crystal violet-iodine complex to leach out of the cells. This allows the cells to subsequently be stained with safranin. At the end of the gram staining procedure, gram negative cells will be stained a reddish-pink color. Remember:
A rod stained with methylene blue will appear blue under a microscope due to the dye binding to cellular components like DNA. In contrast, an unstained rod will appear colorless or slightly transparent. Staining with methylene blue helps to enhance cellular structures for better visibility and analysis.
