Adjusting the Gradient Color
If you do not like the way that the gradient fill looks, you can change the way it looks in the Gradient Tool Options Bar. This bar opens up as soon as you select the gradient tool. This section allows you to change the opacity and mode of the fill. You can also use some of the gradient fills as your fill layer.
But, sometimes these presets still don’t give you the gradient that you want. You can, however, customize the presets further. Select the dropdown box next to the gradient tool icon. This will bring up the Gradient Editor.
Here, you can change the opacity, color, location, gradient type and smoothness. Simply select the preset that you want to use, and then adjust it. If you want to use this preset again, give it a name, and select the New button.
Also, within this dialog box are two Opacity Stop sliders. Use the top Opacity Stop slider to either overlay the gradient over another image or to create a softer transition between the different gradients. Use the bottom slider to adjust the Color Stops, effectively changing the gradient color.
