A transmission type color gradation chart comprising: a color chart member including at least one color bar wherein transmitted light exhibits chromatic color; and a gray gradation chart member wherein transmitted light exhibits achromatic color, and includes a plurality of transmission regions with different brightness, wherein the color chart member and the gray gradation chart member are stacked so that there is a duplicative transmission region wherein the color bar and the plurality of transmission regions overlap in planar view.

A fan blade and color display fan deck provide a changeable color display product because the fan deck blades can be added to and removed from the fan deck without opening the fastener to which the fan blades are pivotally attached. Despite being removable from the fan deck, the blades can withstand the normal wear and tear associated with use in a color fan deck such as supporting the weight of the whole fan deck when a user holds an individual fan blade.

A color display fan deck or a color card has a substrate having a first surface and a second surface. The color display fan deck or color card has a base layer that is applied to one of the first surface or the second surface of the substrate. The base layer has an adhesion promoting material. A process color is applied to the base layer by a digital printing process. A method of manufacturing a color display device is also provided.

There is disclosed a sample holder comprising: a base member; a holder member attached to the base member, the holder member having at least one flexible tab resiliently biased towards the base member; wherein one of the base member and the tab comprises a first formation provided on a face thereof so that a sample having a corresponding second formation can be located between the tab and the base member and retained by cooperation of the first and second formations.

A color display fan deck which illustrates paint colors and a method for making the color display fan deck is described. The color display fan deck includes paper blades which has paint applied on each sized paper surface of each side of the blade. A plurality of planar swatch bearing blades is pivotally joined together at one end to form a deck or fan deck of paper blades painted on each side. The method includes sizing and painting a paper web on both sides with a water based paint having selected heat resistant pigments.
