Paint brush "overlap" darkening

Hello,

I need help in GIMP 2.8.4 when using the paint brush tool to apply color. How do I configure it to avoid this "overlap" darkening effect I'm getting when I paint over previouisly colored areas of my work.

Example : I'm coloring with a wacom bamboo tablet, when I hold the stylus to the pad and paint an area red, it becomes a darker shade of red if i paint over the already painted section. Its a problem because I'm painting manga and there are a lot of really small darker areas that I have to go back and correct which is time consuming

Welcome to Gimp Chat.

Could you post a screenshot of your tool options when you have the brush tool selected please?
It sounds like you have the overall brush opacity at less than 100%.

I have a wacom tablet as well and I'm not sure what the default pressure settings are for the pen, but I'm pretty sure it's not set to 100%, because the harder you press with the pen the opacity will increase.
In the image below, the opacity/pressure of my wacom pen looks to be about 50% or so.
BTW... These are the pen's default settings, except for the 'click sound' box being checked.

Make sure your brush dynamics are set to the "Dynamics off" preset so that you paint at full opacity

(you can save your current Tool options to make them the default when Gimp starts in Edit/Preferences)
