It's been a while since I've played around with it myself, but it is a program specifically designed for making sprites as well as pixel art so you can select pixels specifically. Can't remember about filters, as for color options you do have some there like you can create/import color palettes like if you wanted to work with just the Doom palette and you can indeed do transparency as well as layers, the software even has the ability to do animations within it too.

There's a trial version you can get (can't save files), you could also freely compile the program yourself if you really want.

Here's also the Doom palette I have and a fellow by the name of spritenoob also used this program which I think is where I got my Doom palette. Can't remember exactly.
