Re: how to change the start color in the default palette?
Hello Lily -
It is easy to make palettes.
Create a file with a name of the form: your_file_name.spk
Each line of the file consists of four numbers:
Percent Red_value Green_value Blue_value
The first line should have the value of Percent be 0,
and the last line should have Percent be 100. Values
of Red, Green, Blue range from 0 to 100. An example is
0 0 100 100
20 20 20 100
45 100 100 100
55 100 100 100
80 100 20 20
100 100 100 0
which starts at cyan, goes to blue, to lighter blue,
then to white at the middle, then to light red, to
darker red, and to yellow at the high end.
Then in ferret:
yes? pal your_file_name ! omit the ".spk"
yes? fill variable
The above form persists until a new PAL command is given.
or
yes? fill/pal=your_file_name variable
This form only applies to the individual command and
does not persist.
The initial palette (if you don't change anything) is
called "default".
