When Betelgeuse supernova's, we will know it. It will be brighter than a full moon due to it's relatively close proximity with Earth.
Editing because I just noticed you said 'redder'. Betelgeuse will likely get more red over time, but that's not a change we'd be able to observe with the naked eye. If it's looking redder to you, I'd assume it's just atmospheric conditions where you're at or possibly light pollution in your location. Or, your mind is just playing tricks on you.

Observations by the observers of the AAVSO indicate that Betelgeuse probably reached magnitude 0.2 in 1933 and again in 1942.
At minimum brightness, as in 1927 and 1941, the magnitude may drop below 1.2. Betelgeuse is a semi-regular pulsating red super-giant. It is believed to be at least the size of the orbit of Mars and at maximum diameter may possibly equal the orbit of Jupiter. The star is one of the largest known; spectroscopic studies show that the diameter of the star may vary by about 60% during the whole cycle, a difference considerably larger than the radius of the Earth's orbit!

A Betelgeuse supernova refers to the anticipated explosion of the red supergiant star Betelgeuse, which is located in the constellation Orion. It is expected to be one of the brightest supernovae in recorded history.
While it is impossible to predict the exact date of the Betelgeuse supernova, scientists believe that it could occur anytime within the next 100,000 years.
Yes, the Betelgeuse supernova is expected to be visible to the naked eye, potentially even during the daytime. However, the exact brightness and visibility will depend on the distance of Earth from the explosion and the amount of dust and debris in the interstellar medium.
The Betelgeuse supernova is not expected to have any direct impact on Earth. It is located approximately 642 light-years away, which is too far to cause any harm to our planet. However, it will likely be a spectacular astronomical event to observe.
Scientists will use various telescopes and instruments to observe the Betelgeuse supernova and study its effects. This will include analyzing the light and energy emitted from the explosion, as well as studying the remnants of the star after the explosion, known as a supernova remnant.
