Sugar coating and nicely nicely? I don't think so
It's not so much bright colour as long flowing fins. Which is why male guppies are not reccomended. Bettas are an agressive species by nature so there are quite a lot of even plain fish you shouldn't keep with them.
It also depends on where you got the betta too I think. As discussed in another thread, I think store bought fish who are used to seeing and being with other species stand a better chance of being able to be kept with a variety of tankmates than breeder bought or cup stored fish who see either other males only and flare at them all day, or nothing but the inside of a cup.
Getting lucky with your particular fish doesn't man the species as a whole is fine with bright colours or long fins in tankmates.
