@ Maria ... That is a wonderfully vivid, clear yellow!  I wouldn't have known to look for that, not being much of a car nut, but it's perfect!  :)

@ Costa ... The surrounding blue really sets off the yellow bits of that iris.  Gorgeous stuff!

@ Jacomina ... What a marvellous study in yellows!  I'm impressed you found so many.  :)  I look terrible in yellow ... sort of dead (talk about a nightmare!) ... so it took a while to find something yellow in the house!
