Help With Photoshop Blending Modes

[Anti]

Thanks for your replies.

So, essentially, the colour I see in my mind - how I want the image to look, is not the colour I should be picking. This is hard for me as it seem totally unintuitive.

I will put your advice to practice here and see what I come up with.

I'm so frustrated at this point that I'm ready to scrap PS altogether. Here's hoping I get somewhere with your help.

Thanks!
