Nature Challenge day 1/7 : yellow

My dear blipfriend Susanna challenged me in facebook for the idea of capturing a piece of nature every day during one week and to challenge one of your friends every day. I have decided to share them in Blipfoto, too!  
I will try to find one of the rainbow's colors every day! 

Would you like to be challenged? 

Have a wonderful weekend, my dear friends!
