I'm not sure to understand. In Lightjams, you can dim each fixture type independently if you need to. In other words, don't only use the master intensity if it dims some fixtures too much. Each group has an intensity slider, so use it instead.
In ELM, you can also dim only some fixtures. Select them in the strip list, click edit and use the intensity slider.
There's no way to modify the colors in ELM like that. You can equalize the brightness of your fixtures by using the intensity slider as described before or you can put the different fixture types on different stages to have independent intensity levels.
