Shades of green defined by the government of Bangladesh. Another name for this color is "Bangladesh green". Displayed on the right is the color "bright green". Bright green is a bright shade of green. It is on the color wheel approximately one-third of the way between chartreuse green and harlequin (color #3FFF00) (closer to chartreuse green than to harlequin). Bright green represents a visual stimulus of 556 nanometers on the visual spectrum as measured on the CIE chromaticity diagram. The X11 color "green" is somewhat similar to bright green, with a hex triplet of #00FF00, compared to bright green's triplet of #66FF00. The
Material properties of diamond usually involve irradiation, including proton bombardment via cyclotrons; neutron bombardment in the piles of nuclear reactors; and electron bombardment by Van de Graaff generators. These high-energy particles physically alter the diamond's crystal lattice, knocking carbon atoms out of place and producing color centers. The depth of color penetration depends on the technique and its duration, and in some cases the diamond may be left radioactive to some degree. Some irradiated diamonds are completely natural; one famous example is the Dresden Green Diamond. In these natural stones the color is imparted by "radiation burns" (natural irradiation by alpha particles originating from
