Legacy Colors:

Colors not listed in the table are legacy colors. Legacy couriers were unboxed in the timespan of May 20th - June 25th, 2012. In this timespan there were no pre-defined colors. The unboxed color was generated randomly. Legacy colors are also considered to be truely unique. 2 Example legacies would be:
[218, 42, 101] and [25, 222, 8].

Possible Legacy Couriers

Legacy Couriers could only be obtained in the form of following 6 couriers:
Enduring War Dog, Trusty Mountain Yak, Fearless Badger, Stumpy - Natures Attendant, Mighty Boar, Morok's Mechanical Mediary

and with following 7 effects:
Ethereal Flame, Resonant Energy, Luminous Gaze, Searing Essence, Burning Animus, Piercing Beams, Felicity's Blessing, and Affliction of Vermin

Basics of Color Theory

Color Tones

A color is built up by a combination of red, green and blue parts ranging from 0 (no color) to 255 (full color). Having 3 parts and 256 possible values for each makes up 16,777,216 possible color combinations. If you want to make an orange brighter, use higher values, if you want to make it darker, use lower values.

Examples

[255,255,255] is a perfect white.
[0, 255, 0] is a perfect green.
[128, 128, 128] is a "perfect" grey
[100, 100, 100] is a darker grey
[255, 255, 0] is a yellow
[0, 0, 0] is perfect black
[53, 170, 180] is a teal tone

Are Legacy Colors Unique?

Considering our database stores ~700 legacy couriers. Assume 10,000 Legacies exist which is way over the top.
Math: (16,777,216 possible color combinations) x (6 courier types) x (7 effect types) = 704,643,072 possible unique legacies.
The chance your legacy has an exact duplicate is 1:704,643,072.
In other words: According to official statistics, it's 56,000 times more likely to get hit by a lightning (in your whole life) than your legacy having an exact duplicate.

Note: Getting scammed or hijacked can cause Valve to create a duplicate of your legacy to restore it back to the original account.

Color/Effect parsing in Dota 2

It is important to know, that the colors play an important role in the way the effects are rendered. Low RGB numbers will cause a smaller effect, and big RGB numbers will cause a bigger effect. This means: A 0,0,0 ethereal flame courier will not have any visible difference with a normal, non-unusual courier.
