OpenGL ES 1.1: How to change the color of a texture without losing brightness?

I have particles that I want to be able to change the color of the code, so any color can be used. Therefore, I have only one texture, which basically has brightness.

I used glColor4f(1f, 0f, 0f, 1f);to apply color.

Each blendfunc that I tried that came close to work ends, as in the last picture below. I still want to maintain brightness, as in the middle picture. (This is similar to the Overlay or Soft Light filters in Photoshop if the color layer was on top of the texture layer.)

Any ideas on how to do this without programmable shaders? In addition, since these are particles, I don’t want a black box behind him, I want him to add to the stage.
