One of the most important foundations of painting or rendering with color is the understanding of values using a range of grays bracketed by black and white. In any beginning painting class, a gray value scale is used to compose a picture using varying tones to achieve an overall composition. A student's first painting may only be painted in grays. In my design class, I run my students through a series of exercises rendering interiors in pen and ink and then in gray markers. This lays the groundwork for color in the following semester.
Here's the same interior using markers, which are very fast to use and can save the designer a lot of time. I'm always pushing fast methods of getting ideas to paper using markers and quick sketch techniques.
