Yikes, they sure didn't give you much time to complete this, did they?
One question, what is a Third Race Sticker??
First, about colors that go together well......well, I like shades of blue/green. But you could
also use a purple and lavendar combination. The
important thing is to have
some dark color and
then enough of the medium shade and enough lighter color to complement the dark color. I think you would want mostly medium and light shades of color.
What color paints do you have? This will, of course, affect your choice of color scheme. If you have a blue color, you can always add a little white to it to make a medium blue.....then add more white to make the lighter blue. Then you will have 3 shades of blue to use. You can do this with any color to make different shades.
About placement of the title
Word, you could possibly center
Word slightly above your Bible verse. (Word should be bigger since it is the title.) Then maybe you could place pictures on the board of people at school or in a community setting....and then perhaps place words that evoke what the pictures mean. For instance, the word
helping could be placed by a photo of someone helping another person. You might use other words that show how we spread or share our Christian faith.....like love, kindness, mercy, giving (food, clothes or a Bible), inviting (someone to church or your home), reaching out (to others), etc.
If you don't want to use pictures, try using the words alone. But then you would have to accent the words with decorations.
These are just suggestions....maybe some others have more ideas. It's a little hard trying to describe what I mean......I hope you get the general idea.
