Chameleons change their color through specialized cells called chromatophores. Within these cells, pigments move around in layers to result in a variety of colors.
It depends on the tissue. Most nerves are too small to see individually, but there are bundles that can be viewed with the naked eye or a good dissecting microscope. Nerves can be myelinated, which means that they coated with a fatty layer to speed signal transmission. Most peripheral nerves and those not in the cortex of the brain are myelinated and thus appear white. Unmyelinated nerves are grayish, which is where the term "gray matter" comes from.
