In Photoshop, the "Split Gradient" tool allows you to create a gradient that fades between two colors, but with a distinct line separating the two colors.
Here's how you can use the Split Gradient tool in Photoshop:
1. Open the image you want to work with in Photoshop.
2. Create a new layer by clicking on the "New Layer" button at the bottom of the Layers panel.
3. Select the Gradient tool from the toolbar on the left-hand side of the screen.
4. In the options bar at the top of the screen, click on the gradient swatch to bring up the Gradient Editor.
5. In the Gradient Editor, select the "Split" option from the dropdown menu.
6. Click on the color stops on either side of the midpoint marker, and choose the colors you want to use for the gradient.
7. Adjust the position of the midpoint marker to determine where the gradient will be split.
8. Drag the Gradient tool across the canvas to create the split gradient.
You can also adjust the angle and scale of the gradient by using the options in the Gradient tool's options bar.
