How remove white or one color from image in Photoshop

Select–>Color Range, then select the white. Delete the white. Layer–>Matting–>Remove White Matte to clean up edges. That’s the down and dirty way.

For best results, bezier pen the logo out. Cut into the edges a little and you shouldn’t have white fringes around them.
