Color Selection

I have a question... Probably fairly simple answer. 

 

If I change an image to Paletted and need to select a pixel color for correction - how do i do that? 

 

I know how in photo shop - but im trying consolidate the programs used. 

 

Example - there are a couple stray hot pink pixels amongst the blues and purples. How do i select the pink pixels to change the color of them?
