No, electron microscopes cannot see color like our eyes or optical microscopes can. Electron microscopes use a beam of electrons instead of visible light to achieve much higher magnification and resolution. The images produced by electron microscopes are typically in black and white.

The electrons in an electron microscope interact with the sample differently than light does in an optical microscope. Instead of detecting different colors, electron microscopes rely on variations in electron density within the sample to create contrast in the images. Different materials within the sample will interact with the electron beam differently, leading to variations in brightness and darkness in the final image.

While color is not directly visualized in electron microscope images, scientists can use techniques such as false coloring or image processing to enhance certain features or highlight specific sample elements. However, these colorations are added artificially and do not represent the sample’s natural color.

Differences between optical microscopes and electron microscopes in terms of color:
