At a loss on multi layered masks application

[plumbergp]

Say I have 5 layered masks with color changes in each mask on different parts of the image.

If I set each layer mask to 30% transparency, I can see the effect of all the 5 changes.

But the final colors will not be the ones I selected in the layered masks.

Wondering how to correct for this.

Like to see an example of multi layered masks as the final colors will be distorted.

Thanks.
