How do you get the green like a spruce green? My grass is always to pastel looking....thanks
Use one of the darker green colors to tint the icing. http://www.countrykitchensa.com/catalog/mini.aspx?T=1&ShopId=38&CatId=535&SubCatId=1053 carries several deeper hues of green (link goes to their webpage of food colors).
Try Moss Green
For grass green I like Wilton Moss or Juniper. They're both good, one is just darker than the other.
You can also mess around with green + brown and/or + blue and/or + black.
I use Leaf Green and Juniper Green. For a brighter shade of green I'll add some Kelly green. For icing, make sure you have plenty.
Sometimes I will make a little of both in fondant, then combine a little of each together to have varying shades for leaves. Four or five shades per cake looks more natural than one. I'll even make more than I need, dry and store for spur of the minute cake decorating.
