I painted this cake with regular food coloring. I know there are cake paints on the market that are very much like acrylic paint, but have never looked at them but be assured I will be getting some soon! I started with new paint brushes, a flat brush & a liner brush. Watering down the food color a little and painting from light to dark just like water colors, adding layers of color worked out best & was less stress, too much color and your design could be done for, or at least your fondant. I used the flat brush like a calligraphy pen for the writing and then went over the top with the liner brush. If your brush gets too wet and a lot of color goes on it's easy to fix though, just dry your brush to use it to mop up the extra color like a little sponge. I learned a lot from this little cake. Green & red make brown & black depending on the intensity of either color. So one box of ordinary food color will make just about any color that you need. If ever I make another lemon cake I will stipple the little lemons on the bottom to give them some texture. I chickened out when it came to writing on the cake. I folded under the pressure...I only had 1 box of fondant....I didn't want to ruin it... so I made the banner.
Of course I have already started a little book of cake illustrations & ideas. I did each of these in a matter of minutes, but if time was taken to properly draw them out, I think these could be cool & fun to paint. Paintings of Painted cakes......
