I was trying to make some of my sprites transparent but when I was doing one of the alphablending tutorials it seemed not to provide the desired effect. I filled in the areas I wanted in magenta 255,0,255(I used paint.net) and started spritebatch alphablending , but all i saw was some magenta areas instead of transparent ones. I tried several different options but still i just had magenta ones. Instead I used microsofts DirectX texture tool and it worked, but the magenta method seemed much more effective. Doing the magenta method seemed much simpler though. What can I do? I tried ms paint but when I added magenta I get some small splotches of transparency and still most of it was magenta. What can I do or what steps can I take to make a sprite transparent with magenta or should I just stick with the dx texture tool? Thanks

Have you made sure that the colour is actually 255/0/255?

I had some sprites not working after doing them in paint because paint's default magenta isn't actually 255/0/255 (at least on mine). After drawing the magenta in PS it worked fine.

Edit: Also some editors (like Xara Xtreme) Anti-Alias the drawings so colours might not actually be what you used.

Thanks guys, Not sure what I was doing wrong but after my last try it works.
