blue mew is a shiny version of mew so you have to be very lucky to catch a shiny Pokemon let alone a shiny mew
The only way to get Mew in Pokemon Red, Blue, and Yellow is via the Mew Glitch, which you can find on Bulbapedia.

Mew was a special event Pokemon that was distributed for Pokemon Red and Blue. Mew cannot be found in the wild without cheats or using glitches, which is still possible to obtain. Bulbapedia likely have a great summary about this Mew glitch in Pokemon Red and Blue.
In Pokemon Red, Blue, and Yellow you are able to catch Mew through a glitch. Mew is available in other games such as FireRed and LeafGreen, but it was an event Pokemon. The event it over, and all you can do is wait for a future event, or trade with someone who has Mew.
You can not get a mew in Pokemon Diamond without trading or cheating (HIGHLY NOT RECCOMENDED.) but there is a way to get a mew in the following games: Pokemon Blue, Pokemon Red, or Pokemon Yellow. look up "Mew Glitch" in Google search and find out how. hope this helped!
You cannot catch Mewtwo in Pokemon Crystal, but you can trade it from a Pokemon Red or Blue. Hope this helped :)
There are only 3 ways of getting a mew. 1 cheat with an action replay. 2 mew glich in pokemon red and blue. 3 trade a cheater
Pokemon Blue, Red, and Yellow(special Pikachu Edition) using a GameShark(not recommended) or 1 of 2 of the Mew Tricks. AND Pokemon Emerald(You need an Old Sea Map that you got at a Pokemon Event in Japan in 2005) That is your ONLY chance to catch a Mew.
