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
Diamond color fluorescence characteristics, but no discernible visible absorption spectrum. Type IIa diamond can be colored "pink", "red", or "brown" due to structural anomalies arising through "plastic deformation" during crystal growth—these diamonds are rare (1.8% of gem diamonds), but constitute a large percentage of Australian production. Type IIb diamonds, which account for 0.1% of gem diamonds, are usually light "blue" due to scattered boron within the crystal matrix; these diamonds are also semiconductors, unlike other diamond types (see Electrical properties of diamond). However, a blue-grey color may also occur in Type Ia diamonds and be unrelated to boron. Also not restricted to
