Medium-long forms of the periodic table with element colors.

A limited search for a periodic table with the colors of the elements has not yet located a table of this type. However, Theodore Gray has produced many wonderful tables including one with images of authentic samples of the elements ( ) and a commercially available model that contains sample of most of the elements ( ). While the tables below are not nearly as fascinating or interesting as Gray's tables, the tables below have been designed to enable viewers to focus on the property of color. Most of the colors have been extracted from primarily because it often included a two word description of the color. Other sites referred to were Theodore Gray's and Mark Winter's . For some elements, the colors listed on Internet sites are not always in agreement. Rene Vernon, the author of a paper on metalloids, has contributed valuable comments about the colors of boron, phosphorus, iodine, cesium and astatine. Some of these color issues are because the most stable allotrope (e.g., phosphorus) is not always the most abundant allotrope.

boron - the most stable allotrope of boron is the beta rhombohedral crystalline state. Colors reported for this state range from shiny silver-grey to grey to dark to black. It is represented as dark grey in the table.

phosphorus - the most stable allotrope is black but the most common form is described as white to pale yellow. A very light yellow has been used below with a black insert.

iodine - while silver is sometimes mentioned, the overwhelming consensus is that iodine crystals are in the violet or purple range.

astatine - although astatine has been observed, due to its transient existence, it has apparently not been possible to determine its color. Some web sites conclude that it should have some metallic properties and as a result have a silvery color. Other web sites suggest as progression is made down group 7A (17), the color continuously darkens with a presumption that astatine should be near black. It is left in these tables as unknown like francium and the elements with atomic numbers above 99.

The tables above have been designed to contain elements colored to resemble the actual colors of the elements.  The periodic tables with element colors can also be found at several web sites:
