Steve, I have been wanting to be have numerical gradations of colors for a
long time.
Then, I would be able to use the darkest gradation for the fastest timeframe
of an RSI plotline, then a medium gradation for a medium timeframe RSI plot
line, and finally, a light tone of gradation for the longest timeframe RSI
plot line.
This numerical color gradation system that you have suggested would be a
very useful new Amibroker feature for me. Ron D

Subject: [amibroker] Suggestion: Addition to AFL for color usage
>
> Introduction
> ------------
>
> I would like to formally submit this addition to the AFL (Amibroker
> Formula Language) relating to colors but would first like to gauge
> it's usefulness among those who read this list.
>
> Currently, the way to choose colors in AFL is either through a
> series of predefined color definitions of the form:
>
> <hardcoded keyword "color"><name of color>
>
> For example, colorRed, colorBlue, colorGreeen, colorBrightGreen, etc.
>
> For custom colors, one has to go to the color preferences dialog,
> define a custom color in the bottom section of the color panel and
> then use this form:
>
> <hardcoded keyword "colorCustom"><a number starting at 1>
>
> For example, colorCustom1, colorCustom2, etc. where the principal
> way you know what color you're using is to look it up in the table
> visually and this will vary per Amibroker user depending upon how
> they define that special color table section (i.e., it's not
> portable across Amibroker users).
>
> Suggested Addition to AFL:
>
> Allow colors to be expressed in AFL like this:
>
> colorRGB(R,G,B)
>
> where R represents 256 shades of Red and ranges in value from 0-255
> G represents 256 shades of Green and ranges in value from 0-255
> B represents 256 shades of Blue and ranges in value from 0-255
>
> Examples:
>
> colorRGB(255, 0, 0) // red
> colorRGB(0, 255, 0) // green
> colorRGB(0, 0, 255) // blue
> colorRGB(128, 0, 0) // a half-tone red
> colorRGB(90, 122, 99 // a dark olive tone
>
> Addition to the ParmColor() function:
>
> Assume that you have this somewhere in your AFL script
>
> ParamColor("My Color", colorRGB(90, 122, 99))
>
> Now, in a chart, when you press Ctrl-R to bring up the parameters
> list and then select "My Color" in order to change the color, you
> will get the same Custom Color palette editor to the side of the
> normal one you see now (when changing a color through ParmColor())
> that would allow you to alter the R, G and B values either manually
> or with the black arrow that allows you to change the shading of the
> primary red, green or blue.
>
> If that description didn't sound quite clear, I meant to say you
> will get the same dialog box as the one you see when you select
> Preferences->Colors->Palette Editor in the current version of
> Amibroker.
>
> Notes:
>
> What I like about this addition is that it doesn't break any AFL
> code already in existence yet gives the users a finer grain of
> control over the colors they want to use PLUS the RGB values work
> for everyone's computer whereas the use of colorCustom1,
> colorCustom2, etc. is not transportable across different users'
> Amibroker color usage (custom Color assignments can and will vary
> among Amibroker users.
>
> What do you think?
