Choosing the right color scheme can make your design much more professional. My favorite website for choosing color schemes is ColorHunt.co.
Just click on the color scheme that you like, and then download it as an image.
Open Affinity Photo, and go to the Swatches Panel. Press on the Swatches Panel Menu, and press “Create Palette from Image”.
Then select the image you downloaded from Color Hunt, and change the number of colors to however many colors are in the color scheme. Then press create.
You now have a beautiful color scheme that you can use in any of your designs. Just have an object selected, and then press on one of the swatches to apply a color.
And don’t forget, you can tweak the colors however you want after you apply them to an object. You are an artist. Use your own eyes to make your design beautiful. 🙂
