Usage

Used to create a colour hex code based on a value. Can be used for colour scales from numbers.

{{Color scale
|value  = value (is overridden by specifying Rvalue/Gvalue/Bvalue ; default 0)
|Rvalue = red value   (default 0)
|Gvalue = green value (default 0)
|Bvalue = blue value  (default 0)
|Rmax   = maximum value to scale red channel to   (default 10)
|Rmin   = minimum value to scale red channel to   (default 0)
|Gmax   = maximum value to scale green channel to (default 10)
|Gmin   = minimum value to scale green channel to (default 0)
|Bmax   = maximum value to scale blue channel to  (default 10)
|Bmin   = minimum value to scale blue channel to  (default 0)
}}

Example 1, red scale

{{Color scale| Rvalue = 0 }}
{{Color scale| Rvalue = 3 }}
{{Color scale| Rvalue = 6 }}
{{Color scale| Rvalue = 9 }}

produces → #000000 #4C0000 #990000 #E50000

Example 2, mixed scale

{{Color scale| value = 4.0 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}
{{Color scale| value = 4.5 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}
{{Color scale| value = 5.0 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}
{{Color scale| value = 5.5 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}
{{Color scale| value = 6.0 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}
{{Color scale| value = 6.5 |Rmin=7|Rmax=4|Gmin=7|Gmax=0|Bmin=4|Bmax=30}}

produces → #FF6D00 #D45B04 #AA4809 #7F360E #552413 #2A1218
