i noticed your a beginner trainer, and i'm no expert, but try to check the threads before you start a thread, it was answered in the shiny thread so this is spam, i've made this mistake when i started my account...

If shinies lose their shinyness during evolution we won´t have the sprites of shining Jolteons or shining Ampharos... You could ask this for yourself...
