Hi Joacim, I assume you're trying to tint one of the concrete materials in the Lumion Material Library.
The colour selector in Lumion tints the texture of the material by multiplying each pixel on the texture by the RGB value.
So, unless the texture is pure white, the resulting colour will never be the same as the RGB colour value.
All you can do is to try to compensate for the impact of the texture by increasing the Brightness slider.
