In this tutorial I am going to teach you an awesome way of making a cool green logo.
Step 1
To start off with create a new document (500 by 400 pixels - File > New) and using the Linear Gradient Tool make a green gradient from the top left to the bottom right. The colours that I have chosen are #445e00 for the dark green and #688a02 for the light green colour.
Step 2
Now we are going to be making the basic shape for the logo so create a new layer (Layer > New > Layer) and make a selection like below and fill with white.
Step 3
Next up, move the selection down a bit and to the right, now hit delete. Now you should have something like below.
