Thanks so much everyone for the very quick response! I really appreciate it. I tried and use the Flood Select Tool then use the Flood Fill Tool to fill the colored with white. It works! However some of the lines remain colored and I tried the curve adjustment and it was helpful in changing the colored lines to black. Thanks again. You are all very helpful!

Hi, All I have this colored lined drawing image which I got with permission from the artist. He told me I can change it to non-colored by adding a layer and flooding it with white but it doesn't make sense to me. I only need the black outline of the drawing without the colors. How can I change this colored lined drawing to a non-colored in Affinity Photo? I researched around the forum and read about select sampled color and color replacement tool but it is not working for me or maybe I just don't understand how to use it. Attached is the image for your reference. Your help is greatly appreciated. Thank you so much.
