Site colors
Click a rgb colorpal rowcell to vary a color in the preview field. Click on SetBg takes the background color code to the body background and click on SetFG takes the foreground color code to the body foreground. A click on GetBG/GetFG fetches the color codes from the current body background/foreground, but only when set earlier.
Colors on a screen are displayed in combinations of red green blue (rgb) values. Because each basecolor has 256 shades, the whole spectrum with the three basecolors constists of about 16 million colors. Regard, not each combination possible makes sense. The format of the colorcode is #rrggbb. The rgb #000000 represents nothing equal black, while rgb #FFFFFF is most white. All hexadecimal digits set to equal values show shades of gray. Each of the three basecolor codes consists of two hexadecimal digits. The left and the right digit are controlable by the checkboxes above the preview field. If both are checked, equal color codes are used. If none is checked, nothing occurs (check left, right or both).
Websafe colors
To have websafe colors good for older webbrowsers and systems, a scope of 216 colors supports this when ensuring each single digit of the colorcode is dividable by 3 without remainder. Examle: #FFFF33 meets that condition (F16=1510 devided by 3 results 5 without remainder and digit 3 also).
Netscape 120 color names
Much time ago, Netscape has designed some colors with colornames. There are a lot of colorcodes looking very impressive and not easy to detect when only playing with some arbitrary colorcode ranges. Its shown below ordered by the colornames. The color fields are also clickable to fill the preview field far above.
Site classes
The site most is associated with a style sheet. Click on the link "used css classes" below to get a list of all used css classes on this page. The shown classes are marked as links. When clicked to one, the class name is put in the area below, where the foreground (FB), background (BG) and border (BX) styles are changeable. The changes temporaty apply by a click at "change". Note, the changes are not made with the class itself, because there is no access to a css class. Instead, a style is appended to the affected tags. Any case, the changes are to see immediatly.
