Font and highlight color
 
TreePad uses two different palettes for text and highlight colors, the 16-color drop-down Color list and the Color window, which provides over 16 million (256 x 256 x 256) colors!

Notice that when you change the font background color, this is displayed in the windows of both the Set font color and Set highlight color toolbuttons in the Article and node formatting toolbar.
 
Basic colors
As shown above, the Color window opens showing only the Basic colors (plus two rows of blank boxes for Custom colors, which will be discussed below). This we will call the Basic palette.
 
To change either font color or font background color to one of the Basic colors, highlight the text you want to change, open the Color window using the appropriate command, click the desired color and click OK.
 
Note: Although the Basic palette may appear to contain two or more of the same color (particularly yellow, lime green, aqua and black), these are actually different colors. Should you click Define Custom Colors and compare similar colors by clicking in each and noting their Red, Green and Blue values, you will see they are different! This difference will become more apparent the larger the block of color, and may cause problems for partially colorblind people. It is best always to use the same basic color each time, note its location on the palette, and preferably also note its R,G,B values! True black, for example, has the values 0,0,0.
 
Custom colors
Don't be reluctant to try out Custom colors to find exactly the right font color or font background color; the result may be much more attractive than simply making do with a choice from the Basic color palette.
 
To select a Custom color, highlight the text you want to change, click and click the Define Custom Colors button in the Color window, which will widen to display the Color matrix (window with graded colors), shown here to the right.
 
 
The quickest way to learn about the Color window is to right-click on any region that interests you. A What's This? button will appear. Clicking on it will open a small screen with information about this part of the window. To close this window, press Esc or click outside the screen, in the Color window.
 
 
 
To the right of the color matrix panel is a vertical luminosity slider control.
 
Clicking any color in the Basic palette will move the cross-shaped color matrix cursor to the corresponding color in its panel.
 
Alternatively, click in the color matrix pane to select the color (hue and saturation) you desire, adjust its luminosity if necessary by moving the slider up and down (you will see the Lum value change), and if you are satisfied with the result as displayed in the Color|Solid pane , click OK and the highlighted text will change to this color.
 
Saving and re-using custom colors
If you are likely to re-use a custom color, you can save it in one of several ways:
 
1) Save the block of text containing the color to a file. Paste it in when required and edit the text and any other attributes except the color. This may prove the easiest method.
 
2) Save the color in the Custom colors palette. After adjusting the color to the one you want in the Color window, click the Add to Custom Colors button, then click one of the white boxes in the bottom two rows of the Custom colors palette and the color will be displayed there. You can now select this directly, just as you would one of the Basic colors.
 
Note that you can copy any color from text to the Custom colors palette by highlighting the text, clicking the font color or font background color toolbutton (depending on which color you wish to save), then click the Add to Custom Colors button to save it as described above.
 
3) Save the RGB color values and re-enter them to re-create the color. You can specify any onscreen color in terms of its Red, Blue and Green (RGB) components, which range from 0,0,0 (black) to 255,255,255 (white). As you experiment with the color matrix, you will notice these values changing in their windows. When you have decided on the right color, highlight and copy each of these numerical values to a file and then you can paste or re-enter them when you wish to re-create the color.
 
Clearing custom colors
To reset any box in the two-row Custom colors: palette to the original white, click the box you want to reset, click the white box in the Basic palette, then click Add to Custom Colors. Alternatively, click the box you want to reset so that the color of the Color|Solid box matches it, drag the Luminosity slider all the way up so that the Color|Solid box is white, then click Add to Custom Colors.
 

 
Notes:
 
  1. Only article text can be displayed in more than 16 colors. Note that if an article is in plain text format when a font or highlight color is selected from the Color window, it is automatically converted to rich text format. See Plain text format.
  2. The highlight color can be removed by clicking Main menu ⁄ Format ⁄ Color ⁄ Remove highlight color (see Article text format commands).
  3. Feature unique to TreePad Business Edition.
  4. There are currently no keyboard shortcuts for Set font color or Set highlight color, though menu access keys are available.
  5. Note that when the Color|Solid box is white, you may find that it "sticks" at that color and the Luminosity slider is at the top of its scale and cannot be dragged down. To fix this, click on the Luminosity scale itself and that will reactivate it.
  6. The background "white" color in screen texts may not be pure white but actually a light grey, in order to reduce glare. Although selecting white from the Basic palette in some earlier versions of TreePad resulted in a font background color that was lighter than the standard light grey, resulting in a patchy effect, this has been changed so that standard font background white matches article background white.
  7. Avoid the temptation to use many different colors and styles throughout your articles. You should be very sparing and consistent in their use to maximize their impact.
  8. If you find an attractive color somewhere such as on a Web page or in another program, you can extract its RGB values by using one of several RGB "color picker" programs that allow you to do this. The freeware program Colorer is one of them.
