Your description is confusing.





If you don't know what you are doing you can't describe it. If you can't describe it I can only guess it has something to do with transparency. I doubt some of your words are accurate. Blending? Changing? Random? it may seem that way to you but it probably is not the actual case.





This is a simple procedure.





You ought to get the color you have selected if you click on the swatch in Options Bar while the Brush Tool is activated. Make sure Transparency is set to 0 so the brush stroke completely covers whatever it is painted over.
