Gels are basically "cut" filters. They do not "boost".
They can only cut out parts of the light spectrum that you don't want to see.
If you had a bowl of mixed red and green "M&M" candy and you took out all the green ones, you'd only have half as many M&Ms as you started with.
The solution would be to start with a bigger bowl of M&Ms or else learn to like the green ones.
That means you would need more and brighter lights to start with or else you'll have to use film that responds to tungsten's color spectrum the way you want it.
This is one reason why stages, movie sets and TV studios have so many lights.
