Currently different Channels on Octopus Releases page are all marked with the same colour scheme and you need to read the actual name to distinguish them. Are there any plans to add ability to change their default color and maybe to add some logos etc.
Thanks for reaching out.
Not in our plans, but we are doing something like that in 3.4 for multi-tenancy tags. If you can submit this idea in Uservoice, now would be the right time as its not a bad idea and we are in the code neighborhood: http://octopusdeploy.uservoice.com/
