changing colours

hi

i have picture of a snowman, but certain word wont let me change the colours.... i.e the carrot nose ive changed most but theres a few words than wont let me change it.... HELP!

Small words cannot be changed in Edit mode.
The proper way of doing it is to edit snowman image in any image editor to fill snowman image with colors you want words to be. Then save it and add as your cloud shape by clicking on the first tile in Shapes section.
