Irradiance Theme

Irradiance is the light version of my other theme, Yosembiance.  My goal for this theme is to create something smoother, flatter, and more polished than Ubuntu’s Radiance theme.  I have recently decided to drop the light copper look of Radiance and set the look of my Irradiance-Grey modification as the default Irradiance.

Installation (Ubuntu):

sudo apt-add-repository ppa:bsundman/themes
sudo apt-get update
sudo apt-get install irradiance-theme

    Beautiful! As nice a replacement for Radiance as your Yosembiance is for Ambiance.

    still works with unity?

    • Still works for me on 14.10. Are you having any problems with it?

      • Kotori Bird

    Great theme, thanks a lot.

    If I may ask you a question. Is it possible to add more space around the tree view expand arrow in list view, as in OS X Yosemite?

    This screenshot explains the difference between Yosemite and the Irradiance theme that I’m talking about.

    Thanks again.

    • That’s a good idea. Not sure how soon I’ll get around to it, but I’ll put it on the top of the to do list.

    Unfortunately did not change anything for me. Is there any thing else I need to do after installation?
    PS: I am on Ubuntu 14.04

    Wow, excellent theme, I’m using it on Ubuntu MATE 14.04, I like to give you feedback to keep working on this wonderful light theme 🙂

  • Matias

    I have to say. this theme is incredible. It’s very polished and I haven’t seen yet any rough edges. Thank you Mr. Sundman for this excellent work!

  • nice themes. thanks. 🙂

  • Federico Ponzi

    Just installed this on Mint and it works!

  • Kotori Bird

    Will u give support to Wily Werewolf on the ppa?

    • My next update will definitely be for Wily, but the earliest I can start working on it is mid December. My guess is that the release will be later in January. It will be a complete rewrite which is necessary going forward with the latest versions of Ubuntu and gtk, so there is a chance it may take longer than expected.

    What a pity this is current unavailable and incompatible with Ubuntu 16.04/Gnome 3.18+. It is a very beautiful theme. I hope you update it as you have Yosembiance.

    Thank you so much for your work! 🙂
