Free colors and software for linux

colorsvn is the Subversion output colorizer.
colorsvn was extracted from kde-sdk and was extended with build process and configuration.
Basic Installation:
./configure
su -
make install
Perhaps you want to set alias to svn:
alias svn=colorsvn
So if you type "svn" youll run "colorsvn".
Enhancements:
- Subversion commands for color highlighting are configurable now.
- For directories, a bold font will be used.
- Colors will be applied only for configured terminal types.
- Erroneous configured colors will be filtered.
- There are minor installation bugfixes.

Color Label is a service menu for KDE based on Color Folder 0.3.4 by HessiJames.

HowTo:

Extract all files and

copy colorlabel into /usr/bin/...

perhaps you need to make it executable chmod 755 /usr/bin/colorlabel

copy colorlabel.desktop to /home/~/.kde/share/apps/konqueror/servicemenus/colorlabel.desktop

Imager::Color is a Perl module with color handling for Imager.

SYNOPSIS

$color = Imager::Color->new($red, $green, $blue);
$color = Imager::Color->new($red, $green, $blue, $alpha);
$color = Imager::Color->new("#C0C0FF"); # html color specification

$color->set($red, $green, $blue);
$color->set($red, $green, $blue, $alpha);
$color->set("#C0C0FF"); # html color specification

($red, $green, $blue, $alpha) = $color->rgba();
@hsv = $color->hsv(); # not implemented but proposed

$color->info();

if ($color->equals(other=>$other_color)) {
...
}

This module handles creating color objects used by imager. The idea is that in the future this module will be able to handle colorspace calculations as well.

new

This creates a color object to pass to functions that need a color argument.

set

This changes an already defined color. Note that this does not affect any places where the color has been used previously.

rgba

This returns the rgba code of the color the object contains.

info

Calling info merely dumps the relevant colorcode to the log.

equals(other=>$other_color)
equals(other=>$other_color, ignore_alpha=>1)

Compares $self and color $other_color returning true if the color components are the same.

Compares all four channels unless ignore_alpha is set. If ignore_alpha is set only the first three channels are compared.

You can specify colors in several different ways, you can just supply simple values:
simple numeric parameters - if you supply 3 or 4 numeric arguments, you get a color made up of those RGB (and possibly A) components.

a six hex digit web color, either RRGGBB or #RRGGBB
an eight hex digit web color, either RRGGBBAA or #RRGGBBAA.
a 3 hex digit web color, #RGB - a value of F becomes 255.
a color name, from whichever of the gimp Named_Colors file or X rgb.txt is found first. The same as using the name keyword.

You can supply named parameters:

red, green and blue, optionally shortened to r, g and b. The color components in the range 0 to 255.

# all of the following are equivalent
my $c1 = Imager::Color->new(red=>100, blue=>255, green=>0);
my $c2 = Imager::Color->new(r=>100, b=>255, g=>0);
my $c3 = Imager::Color->new(r=>100, blue=>255, g=>0);
hue, saturation and value, optionally shortened to h, s and v, to specify a HSV color. 0 new(hue=>120, value=>1, saturation=>0.5);
web, which can specify a 6 or 3 hex digit web color, in any of the forms #RRGGBB, #RGB, RRGGBB or RGB.
my $c1 = Imager::Color->new(web=>#FFC0C0); # pale red
gray or grey which specifies a single channel, from 0 to 255.
# exactly the same
my $c1 = Imager::Color->new(gray=>128);
my $c1 = Imager::Color->new(grey=>128);
rgb which takes a 3 member arrayref, containing each of the red, green and blue values.
# the same
my $c1 = Imager::Color->new(rgb=>[255, 100, 0]);
my $c1 = Imager::Color->new(r=>255, g=>100, b=>0);
hsv which takes a 3 member arrayref, containting each of hue, saturation and value.
# the same
my $c1 = Imager::Color->new(hsv=>[120, 0.5, 1]);
my $c1 = Imager::Color->new(hue=>120, v=>1, s=>0.5);

gimp which specifies a color from a GIMP palette file. You can specify the filename of the palette file with the palette parameter, or let Imager::Color look in various places, typically "$HOME/gimp-1.x/palettes/Named_Colors" with and without the version number, and in /usr/share/gimp/palettes/. The palette file must have color names.

my $c1 = Imager::Color->new(gimp=>snow);
my $c1 = Imager::Color->new(gimp=>snow, palette=>testimg/test_gimp_pal);

xname which specifies a color from an X11 rgb.txt file. You can specify the filename of the rgb.txt file with the palette parameter, or let Imager::Color look in various places, typically /usr/lib/X11/rgb.txt.

my $c1 = Imager::Color->new(xname=>blue) # usually RGB(0, 0, 255)

builtin which specifies a color from the built-in color table in Imager::Color::Table. The colors in this module are the same as the default X11 rgb.txt file.

my $c1 = Imager::Color->new(builtin=>black) # always RGB(0, 0, 0)

name which specifies a name from either a GIMP palette, an X rgb.txt file or the built-in color table, whichever is found first.

channel0, channel1, etc, each of which specifies a single channel. These can be abbreviated to c0, c1 etc.

channels which takes an arrayref of the channel values.

Optionally you can add an alpha channel to a color with the alpha or a parameter.

These color specifications can be used for both constructing new colors with the new() method and modifying existing colors with the set() method.

Splashy for Edgy project paints graphic images directly to framebuffers using libdirectfb.

Splashy is a boot splash program that doesnt require patching the Linux kernel. Splashy project paints graphic images directly to framebuffers using libdirectfb.

VGA settings
-----------------------------------------------------------------
640x480 800x600 1024x768 1280x1024
256 colors 768 771 773 775
32K colors 784 787 790 793
64K colors 785 788 791 794
16M colors 786 789 792 795
-----------------------------------------------------------------

For 1024x768 at 16bit (64K colors or "thousands of colors") you could pass an argument to the kernel like:

vga=791

These values could be used in base16 also (hexadecimal) like:

vga=0x317

To pass arguments to the kernel, you would need to edit your boot-loader:

1. Grub /boot/grub/menu.lst
hint, in debian, look for "#kopt" and append vga=0x317 to that line. Then run update-grub. Other distros edit the kernel root= line appropriately
2. Lilo /etc/lilo.conf
hint, look for the default image= and edit append= by appending vga=0x317 to it
3. Quik /etc/quik.conf
on PPC machines. Append vga=0x317 to the kernel argument line

Resistor Color Code Calculator project calculates the value of a resistor (an electronic component).

The colors on the resistor are input into the program, and the result displays the resistance value of the resistor.

This is much easier than memorizing rhymes to remember colors.
