HTML colors

In an HTML page, the colors are represented by a character string such as "#RRGGBB". RR, GG and BB represent the hexadecimal value of red, green and blue components.
The following code allows you to convert an HTML color into an RGB color:
nRGB is int
HTMLColor is string
// If the HTML color has no #
nRGB = RGB(Val(Left(HTMLColor, 2), "x"), ...
Val(Middle(HTMLColor, 3, 2), "x"), ...
Val(Right(HTMLColor, 2), "x"))
// If the HTML color contains #
nRGB = RGB(Val(Middle(HTMLColor, 2, 2), "x"), ...
Val(Middle(HTMLColor, 4, 2), "x"), ...
Val(Right(HTMLColor, 2), "x"))
You can also use RGBToHTML.

RGB and code editor

In the code editor, when the RGB function and its parameters are specified, a square appears automatically, showing the corresponding color:
A click in the colored square is used to open the color picker.
Color picker
If the color is modified, the modification is taken into account when validating the color picker.

Miscellaneous

  • The colors specified with RGB can be modified according to the capacity of the current screen mode (VGA, 32 colors, etc.).
  • Important: It is recommended to specify colors using the color constants defined in WLanguage (see the preset colors of WLanguage).
