Crisp White Background without whitewash

I am having a hard time getting blender to render white. pure crisp white.
Without whitewashing the rest of the scene.

in the example below. The text is a image as plane import I add planes over the letters and fade the material. But I can not get it nice crisp withe it’s off geryish. Playing with the exposure and gamma whitewashes the image.

Can anyone tell me how to do this?

Render2

Change the color management from filmic to default

Thanks I have tried that, Will play with it a bit more ans see
