The colors logo is a trademark of Viacom 18. So they cant go with the TV18 branding on this one. It has to Viacom18 if they are including the Colots Logo
If at all TV 18 goes for a sports channel, They Could use Colors branding with branding license from Viacom18, or it could be Sports 18 as they have news 18.
else it could well be JIO Sports, as it is on JIO TV
Here I made the logo of colors Malayalam. This is not an exclusive one. Ours members tried it earlier.
Following Zee, chances are now existing for naming as 'Colors Keralam'.
