Chromatics Inc. was a color graphics display manufacturer based in Tucker, Georgia. [1] Their systems predated the personal computer era of inexpensive graphics displays, and were typically used as peripheral devices, connected to a mainframe or minicomputer. In some configurations, a Chromatics graphics terminal could be used as a stand-alone ...
The Atari ST series has a digital-to-analog converter of 3-bits, eight levels per RGB channel, featuring a 9-bit RGB palette (512 colors).Depending on the (proprietary) monitor type attached, it displays one of the 320×200, 16-colors and 640×200, 4-colors modes with the color monitor, or the high resolution 640×400 black and white mode with the monochrome monitor.
Since these new colors are the result of cross-color artifacting, they are often called "artifact colors". Both the standard 320×200 four-color and the 640×200 color-on-black graphics modes could be used with this technique. Early efforts resulted on a usable resolution of 160×200 with 16 colors. [24]
A different set of 16 simultaneous colors is available using an NTSC TV or composite monitor by using artifact color techniques, with independent groups having demonstrated much larger color sets of over 256 colors See Color Graphics Adapter#High color depth. The CGA RGBI palette is a variant of the 4-bit RGBI schema, arranged internally like ...
Color 6 is treated specially; normally, color 6 would become dark yellow, as seen to the left, but in order to achieve a more pleasing brown tone, special circuitry in most RGBI monitors, starting with the IBM 5153 color display, [11] makes an exception for color 6 and changes its hue from dark yellow to brown by reducing the analogue green ...
Simulated Hercules InColor Card 640 x 350 x 16 graphics resolution and color abilities, corrected for aspect ratio. The Hercules InColor Card (GB222) is an IBM PC compatible 8-bit ISA graphics controller card released in April 1987 by Hercules Computer Technology, Inc. [1] [2] [3] It supported a fixed hardware palette of 64 colours, with the ability to display 720 × 350 with 16 colours on an ...
Cromemco systems were also broadly adopted by U.S. television stations for generating weather and art graphics, using software developed by ColorGraphics Weather Systems. By 1986 more than 80 percent of the major-market television stations in the U.S. used Cromemco systems to produce news and weather graphics. [60]
Creator was set up to be a modular system, tailored to the specific needs of each "shop" or user. The base for version 7.0 was the "CT-Brix" software library (colour selection, basic compositing, selection, transformation, shapes, basic colour correction, densitometer, layers etc.), also featured in other Barco Graphics CT (continuous tone) products, e.g. ColorTone.
