Introductory to Forum and Question about Color Overlay

hey there guys its nice to meet you . It is my first time here and I am exploring graphic design on my own as an full time architect student. Now that school is over for the year I actually want to learn skills in graphic design and I’m beginning with looking at designs from pinterest and how is it achieved. An example would be this poster, How does one achieve these colours over an image other than using the colour overlay because when I used the overlay I had to change the opacity which resulted in the true color of the image to seep through - not a good look . so any method will be greatly appreciated . Thank you and be safe :slight_smile:
