The color filter adjustments almost NEVER work right. It will not help you to have a red filter. I probably used color filters on 40 or 50 different TVs and there was never a "perfect" result with any of them. So I stopped using the filters. If you are going to adjust your result with your eyes when you are done using the filter... why bother using the filter then? Just use your eyes.
If you think the picture has too much red, try the next "cooler" color temperature setting. If you are using Warm2, change to Warm 1. If you are using Warm 1, change to Neutral or Standard or whatever the manufacturer has named it. Color temperature settings change the balance of red and blue.
"Red push" is something that was a problem for CRT video displays that does not seem to be an issue for digital displays (at least not since 2006 or so when I began measuring and evaluating consumer video displays). Having too much red, is NOT the same thing as red push. Red push was a result of how manufacturers designed the analog color decoder. There is no analog color decoder in video displays, you convert the video to YCbCr to be processed by the TV and just before display, the TV converts the data to RGB. The manufacturer COULD simply have the red gain set too high (or you could have a color temperature selected that is too warm).
If the problem is not the color temperature setting and you have too much red because the Red Gain control is set too high by the manufacturer, you can try reducing the Red Gain control and watching some video for 2 or 3 days to see if the red is better. If the red is not better or it is too weak, make another adjustment and watch more video for 2 or 3 days to see what you think of red in a wide range of TV programs or movies. Red Gain will be one of the CMS controls (color management)... different manufacturers have different names for these controls in their User Menu (might also be called Red High). But to KNOW you have the correct settings for RGB gain controls (and RGB offset controls) you really must have a meter and calibration software. Or hire a professional calibrator -- you can check the THX and ISF web sites to see if there are trained calibrators in your country. THX has been doing a lot of international calibration training classes.
There really is no easy way to set color balance correctly with your eyes. This is because your eyes "adapt" to color and luminance/brightness (actually, it is your brain that "adapts", not the eyes). This is why optical illusions exist (black and white and color illusions are both easy to demonstrate and there are many places on the internet to see optical illusions.
