On August 11th, 1951 1951, CBS produced a colorcast (using their semi-mechanical, non-compatible color TV system) of a game between Brooklyn and the old Boston Braves at Ebbets Field. As far as I know, the first colorcasts of baseball in the NTSC system were the 1955 World Series on NBC. The First Rose Parade Color CastNBC, January 1, 1954. This was the first ever national west coast – to east coast colorcast using the newly approved National Television System Committee (NTSC) standards.

- Cast is an ideal class of acrylic to use when fabricating. This includes drilling, polishing, gluing etc.
- Most cut pieces will require a saw cut that may take off 1/8 of an inch from the length and width. Special requests can be made for additional fees.
- Tolerances vary greatly in this type of acrylic.
This cell-cast sheet has many applications ranging from display, furniture and fabrication. It is a higher grade then the extruded sheet. Comes in wide variety of colors and thicknesses. Paper masked.
A colour cast is a tint of a particular colour, usually unwanted, that evenly affects a photographic image in whole or in part.[1]
Certain types of light can cause film and digital cameras to render a colour cast. Illuminating a subject with light sources of different colour temperatures will usually cause colour cast problems in the shadows. The human eye generally does not notice the unnatural colour, because our eyes and brains adjust and compensate for different types of light in ways that cameras cannot.
In film, colour casts can also be caused by problems in photo development. Improper timing or imbalanced chemical mixtures can cause unwanted casts.
Colour casts can also occur in old photographs due to fading of dyes, particularly under the action of ultraviolet light. These may be correctable on a scanned version of the photograph with image editing techniques.[2]

Most digital cameras try to automatically detect and compensate colour cast and usually have a selection of manually set white balance settings to choose from. Otherwise, photo editing programs, such as Photoshop, often have built in colour correction facilities. For film, blue filters and amber filters are used to counter casts. Amber filters are used to reduce the blueish tint caused by daylight. Blue filters reduce the orange colour caused by incandescent light.
A variety of coloured filters in varying degrees of intensity are available. Kodak's amber filters, for example, vary from palest yellow ('81C') to deepest amber ('85B'). A photographer chooses which filter to use based on the quality of the ambient light. Colour temperature meters can read the temperature of the existing lighting conditions and guide the selection of the filter. Clouded sky, for example, requires a paler amber than clear blue sky. If a filter is unavailable, flash is an alternative solution which usually provides enough neutral white light to counter the cast.
In the case of film, if photographs all contain the same cast, it is usually indicative of improper chemical development. If the film itself does not contain any cast, it can be reused to create another set of photographs in proper chemical conditions. If the film contains a cast, filters can be used during photo processing to correct it.
