r/linocut

Hi, I am very new to linocuts, foreign speaker, please bear with me and my terminology. After a few tries I cut a block I am happy with and would like to print it on a cotton t-shirt. I purchased an acrylic-based linocut paint specifically for textile. However - it’s white and I want to print on a black tee. So far all my attempts ended with an ugly grayish print very far from the contrast hue I’d like. How does one correctly apply paint to the block? One thin layer doesnt seem to work. Thank you so much for advice
