question:
There are two kinds of primary colors: those you get by combining light (these are called "additive") and those you get by mixing pigments (these are called "subtractive"). As many computer users know, the additive colors are red, green, and blue. Traditionally, the subtractive colors were red, yellow, and blue. But more technically, they are magenta, yellow, and cyan (a kind of blue).

question:
Visual Basic is a programming language and software development environment created by Microsoft in the 1990s primarily to make it easy for developers to create client applications on Windows. It featured an way to easily create graphical user interfaces by drawing windows and controls on the screen, and an event-driven paradigm that made it easy to attach code to meaningful events in the lifetime of an application (such as a button click).

The language was adapted to the Web with a variant called VBScript, and embedded into Microsoft Office and other applications with another variant called Visual Basic for Applications (VBA). Around the time of Windows 98's release, it became possible to create scripts written in VBScript to run on the Windows desktop.

In 2000 Microsoft introduced a new unified framework for software development called .NET. At that time Visual Basic was thoroughly revised and renamed to Visual Basic .NET. This version of the language added some capabilities, but dropped others, and was incompatible with previous versions of the language, leading some to complain that it should be been released as a separate language with a different name. Still, a great deal of Visual Basic code is in use today and large numbers of developers still use it to create client applications, Web apps, script, and macros embedded in other applications such as Microsoft Excel.
