What is Delta value on color?

Delta-E (dE) is a single number that represents the ‘distance’ between two colors. The idea is that a dE of 1.0 is the smallest color difference the human eye can see.

A Delta E between 3 and 6 is usually considered an acceptable number in commercial reproduction, but the color difference may be perceived by printing and graphic professionals. (Note: Human vision is more sensitive to color differences if two colors actually touch each other).

What is sRGB used for?

The sRGB color space is composed of a specific amount of color information; this data is used to optimize and streamline colors between devices and technical platforms, such as computer screens, printers, and web browsers. Each color within the sRGB color space provides the possibility of variations of that color.

When a system E is always negative?

E is negative when the system does work on its surroundings. E > 0) when the system gains heat from its surroundings or when the surroundings do work on the system. The system is usually defined as the chemical reaction and the boundary is the container in which the reaction is run.
