Color charge is a property of quarks and gluons that is related to the particles' strong interactions in the theory of quantum chromodynamics (QCD). Like electric charge, it determines how quarks and gluons interact through the strong force; however, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue.
The TI-84 Plus C Silver Edition was released in 2013 as the first Z80-based Texas Instruments graphing calculator with a color screen.It had a 320×240-pixel full-color screen, a modified version of the TI-84 Plus's 2.55MP operating system, a removable 1200 mAh rechargeable lithium-ion battery, and keystroke compatibility with existing math and programming tools.

The CX series were released in the same time frame as the Casio Prizm (fx-CG10/20), [10] Casio's color screen graphing calculator with similar features. The TI-Nspire CX series differ from all previous TI graphing calculator models in that the CX series are the first to use a rechargeable 1,060 mAh lithium-ion battery (upgraded to 1,200 mAh in ...
According to quantum chromodynamics (QCD), quarks possess a property called color charge. There are three types of color charge, arbitrarily labeled blue, green, and red. [nb 6] Each of them is complemented by an anticolor – antiblue, antigreen, and antired. Every quark carries a color, while every antiquark carries an anticolor. [76]
The three kinds of charge in QCD (as opposed to one in quantum electrodynamics or QED) are usually referred to as "color charge" by loose analogy to the three kinds of color (red, green and blue) perceived by humans. Other than this nomenclature, the quantum parameter "color" is completely unrelated to the everyday, familiar phenomenon of color.
Each is a scalar field, for some component of spacetime and gluon color charge. The Gell-Mann matrices λ a are eight 3 × 3 matrices which form matrix representations of the SU (3) group . They are also generators of the SU(3) group, in the context of quantum mechanics and field theory; a generator can be viewed as an operator corresponding to ...

The original TI-30. The TI-30 is a scientific calculator manufactured by Texas Instruments, the first model of which was introduced in 1976.While the original TI-30 was discontinued in 1983 after several design revisions, TI maintains the TI-30 designation as a branding for its low and mid-range scientific calculators.
