Changing my Watermark

One reason to keep components on their own layers is that they are easier to adjust. I like your logo, but the black lines need to be fixed before you go live with this. In Photoshop, you can apply a Stroke as a layer style.

If you have Illustrator, though, it is preferred for this kind of drawing because it is vector and can be resized. Photoshop is raster.

If you'd like the white background to be black, the black type and outlines to be white, and the color portions to stay the same then you can invert the image but preserve the color as a duplicate layer with a layer mask. Here's how (assuming the graphic is flattened):

1. Duplicate the layer that contains your image (right-click in the Layers panel and select Duplicate Layer...)
2. Click on the eye to the left of the new layer to hide it temporarily
3. Select the original layer
4. Invert it (Image > Adjustments > Invert or Control (PC)/Command(macOS) + I)
5. Select the duplicate layer
6. In the Toolbar, select the Quick Selection Tool (if you can't find it, use the Discover panel to search for it (Help > Photoshop Help)
7. Draw on the green portion, hold Shift, draw on the blue portion, and draw on the coral portion (if you select too much, you can use a smaller brush &/or zoom in)
8. At the bottom of the Layers panel, click the 3rd button from the left to make a layer mask
