Suppose I have a linear integer scale with GREEN assigned to the uppermost scale value and RED to the lowest scale value. YELLOW is assigned to the median scale value. (Like a traffic light that uses HTML color codes.)
If my scale is from 0 to 2, my color choices are easy.
- 2 = BRIGHT GREEN
- 1 = BRIGHT YELLOW
- 0 = BRIGHT RED
When I have a larger scale, then it's more difficult. For instance, if my scale is from 0 to 10.
- 10 = BRIGHT GREEN
- 9 = GREEN
- 8 = DARK GREEN ?
- 7 = ???
- 6 = ???
- 5 = YELLOW
- 4 = ???
- 3 = ???
- 2 = DARK RED ?
- 1 = RED
- 0 = BRIGHT RED
It's worse when the scale goes from 0 to 100?
There must be a CPAN module to help choose these (web-safe) colors, but I can't find one via searching...
Color::Calc::WWW
Color::Library::Color
Thanks for your help!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
