Getting so confused with the color issue. Back a couple questions I pluralized marron: ces chaussures sont marrons...and it was incorrect. Read the comments and I thought I understood. Colors agrees in gender/number if they represent something in real world (e.g. roses, violet). Wait, now getting confused again just thinking about THAT. Basic question here is, why is yellow pluralized in this sentence. Should it not be: mes chaussures sont jaune?
