The scale of 0 ~ 100 represents "precentage of black".
You should be able to see 11 distinct shades ranging from white (0 percent black) to solid black (100%). If you can not distinguish, for example, 90 versus 100 percent, then your monitor needs adjustment to see the swatches more accurately.
Your monitor should also display each of the primary colors correctly. From top to bottom: Cyan, Magenta, Yellow (CMY) and Red, Green, Blue (RGB).Each of these colours are very disitinct. As an example, if yellow looks similar to green, then your monitor is not showing colours correctly and needs adjustment.
For design professionals: please make sure your monitor is color calibrated for the best representation.
Note: Many LCD monitors (this includes laptops) can not display colours accurately due to a limited colour gamut.
The Accuswatch scale indicates that the swatch has been reproduced "to scale" and it has also been "color corrected" to reduce imperfections introduced in the scanning process. The 1 inch and 1 cm markers represent a section of the fabric, or finish, of relative size.
Note: due to techical issues with scanners and imaging technologies -- or the equipment and software you are using, the actual fabric may look different.
DISCLAIMER: Due to colour variations on different monitors and color printers, if you are concerned about exact colour and texture matches, etc. and wish to clarify, we recommend that you first request a sample, to ensure proper colour representation. Please contact your local Global Dealer for more information or to order a sample. Global cannot be held responsible for any selections of colors from this website.
