Hello, Here is the logo I came up with for your show/podcast. The "T" doubles as a cross with the light coming from behind it (the meanings there are multiple). Also, if you ever needed an alternate smaller icon, you could just use the T Cross with the sunburst behind it! I chose warm yellows and oranges to go with the cool, calm blues--they look great together and they also evoke hope, happiness, etc.
Let me know your thoughts and if you have settled on any specific color-schemes yet or not, and we can go from there. Thanks for looking!
As you can see, the borders allow for it to look great on virtually any color. It might be cool to change the colors each week to coincide with your overall theme or message.
