The colors used for "Figure 1.1 OSGi layered architecture" are pretty dark, with the middle and bottom components almost blending. A suggestion would be to use some lighter colors, possibly gradients. It was mentioned on one of the threads in the forum that you are using OpenOffice, is so then you can easily change the background of each component.

Top-component: Right-click on the top component, from the pop-up menu select "Area". In the Area Window, select the Gradient Tab. In the tab, select the Linear Blue/White [don't worry it will be soon be a nicer green]. In the left properties column [if you look the window is really divided into three columns, with the color selection being the middle one], in the left column select the "From" color. A selection should appear, scroll down until you see 'Green 6', choose this color. Now in the right column click on the "Add" button, a pop-up window will appear, you have a choice, accept the default gradient color name, or provide one.

Middle-component: Repeat the same steps as above, in the "From" color, choose 'Orange 3'.

Bottom-component: Repeat the same steps as in the Top-component, in the "From" color, choose 'Red 1'

The above example will result in some light colors, more attractive, and subconsciously more positive. Which is nicer? Dark dreary colors, or brighter ones?

Re: Chapter 1, Page 9, Colors
Done. Of course, I am not sure if the colors in our figures will be the precise ones used in the book, but we shall see! smilie
