#!/bin/bash
if [ $clr="r" ]; then
echo -e '\E[1;31m'
fi
Notes:
Removed surrounding spaces around the '=' (doesn't like extra spaces)
Removed extra space after closing square bracket (not major)
Changed escape character at beginning of string to '\E' (can't remember the difference)
Used single quotes for the string (apparently recommended but optional)
Added 'fi' to terminate the 'if' command (compulsory)

convert::color::hsl
Convert::Color::HSL(3pm) User Contributed Perl Documentation Convert::Color::HSL(3pm)NAME
"Convert::Color::HSL" - a color value represented as hue/saturation/lightness
SYNOPSIS
Directly:
use Convert::Color::HSL;
my $red = Convert::Color::HSL->new( 0, 1, 0.5 );
# Can also parse strings
my $pink = Convert::Color::HSL->new( '0,1,0.8' );
Via Convert::Color:
use Convert::Color;
my $cyan = Convert::Color->new( 'hsl:300,1,0.5' );
DESCRIPTION
Objects in this class represent a color in HSL space, as a set of three floating-point values. Hue is stored as a value in degrees, in the
range 0 to 360 (exclusive). Saturation and lightness are in the range 0 to 1.
CONSTRUCTOR
$color = Convert::Color::HSL->new( $hue, $saturation, $lightness )
Returns a new object to represent the set of values given. The hue should be in the range 0 to 360 (exclusive), and saturation and
lightness should be between 0 and 1. Values outside of these ranges will be clamped.
$color = Convert::Color::HSL->new( $string )
Parses $string for values, and construct a new object similar to the above three-argument form. The string should be in the form
hue,saturation,lightnes
containing the three floating-point values in decimal notation.
METHODS
$h = $color->hue
$s = $color->saturation
$v = $color->lightness
Accessors for the three components of the color.
( $hue, $saturation, $lightness ) = $color->hsl
Returns the individual hue, saturation and lightness components of the color value.
