Pixelated logo
Hi,
I'm trying to change the color of a logo (and maybe even the font), but it gets very pixelated. I`ve tried these ways of coloring :
1. One is by using the magic wand, inverse and then fill solid color.
2. The other one is by clicking on the little half white and half black circle next to the layers and put hue saturation.

However, in both ways, the result is very dirty, smudged and pixelated.
How can I make it more clean and sharp? Because it`s very unpleasant to look at.
Thank you!
