Red cloth is commonly used in Pooja, and you put Red tika (and rice grains) on forhead. Brides traditionally wear predominantly red clothes for certain ceremonies during wedding. Red, Yellow/Amber, and White are quite common during rituals in North. Are they not in South India?

This isn't common in south India (to my knowledge).

Yellow is the one that stands out to me, and has religious connotations of purity and sacredness, but not red. (White too does, but for non-religious reasons, including associations with Khaddar and with Dhotis.)
(From another response:)
> All Goddesses wear red colored clothes
In my region, the colours change every day (or in some similar regular interval), and red isn't significantly more prominently used than others.
I can see a sort of link made via the Kumkum/Tika/Tilaka from red to purity, but honestly that would be a stretch and a pretty unlikely association for someone to make when encountering the colour.
