I feel like it’s really difficult to realistically portray suns in CG, as there are too many factors to go along with it.

If we are talking from a realistic standpoint, those two suns would both be extremely white (or atleast one of them would be very slightly red) without the atmosphere due to lack of Rayleigh scattering (this is the reason why the sky is blue; the sun hits the atmosphere and in turn blue light is scattered more in the spectrum and the sun looks slightly yellow or red from the lack of the blue light.)

Also you have to consider the anamorphic lens flare, how bright you want the suns to be? (I presume they are in the Goldilocks region in which the sun is not too close, nor too far which can inhabit life so they’d be pretty bright if you point a camera at it) and the way it looks overall in terms of volumetric lighting and many, many factors which are insanely hard to pull off. Besides, the two suns are insanely close to each other that when viewed from space theyd look like a single giant light source.

For reference, here is how the sun actually looks like in space:

This is one of the reasons why you don’t actually see the sun nor the light source in Star Wars, since its very difficult to pull off. These shots were planned to avoid the light source to be shown.

However, I am thinking of planning two shots, mainly the first shot showing the Falcon leaving the homestead with the suns slowly rising up in the sky (as it has been stated here that this scene takes place at dawn) and the second of the planet to simply leave the Tatooine horizon and jump into hyperspace which then iris wipes to the credits.
