When web developers specify color values for text or backgrounds, they often represent RGB (red-green-blue) colors using a six-d
igit hexadecimal (base-16) value, such as #bf5700, in which the first two characters represent the red component of the color, the middle two characters represent the green component, and the final two characters represent the blue component. Each of these color components can be assigned one of 256 different values (decimal: 0 – 255, hexadecimal: 00 – ff), with lower values representing darker shades and higher values representing brighter shades. You want to configure the text on your blog to use a slightly darker shade of purple than the one you have seen used on another website. The purple used on that site has an RGB value of #7f20ff. Which of the following RGB values would produce the darker shade of purple that you desire for your blog?
(A) #3f107f
(B) #7f60ff
(C) #aa33ff
(D) #002000
Letter B would produce a lighter blue-purple color rather than a darker shade of purple. Letter C would produce a very light purple color. Letter D would produce a Black color, making it very dark and not in the range of being purple.
Letter A would produce a darker shade of purple. As explained in the way that the RGB color hexadecimal uses, the amount of each respective color is 2 digits for each color Red, Green, Blue respectively. By reducing the amount of each color in the RGB mode, the output will become a darker shade as the RGB mode is an ADDITITIVE type of color mode.
The basic objective of software engineering is to develop methods and procedures for software development that can scale up for large systems and that can be used consistently to produce high-quality software at low cost and with a small cycle of time.
