Donate button designs

I thought I'd give the client a simple image as an option just in case they want a more subtle approach to gaining donations.

A smiley face to symbolise what you would be doing by giving the charity a donation.

I designed this balloon to use wish upon a stars colours and to represent hope for the children and families through the use of the star. I also think it will unite the branding through its connection with the logo.

I don't like the colours of the balloon although I thought I'd try it out as it goes with the colour of Wish upon a star.

This is my favourite design so far as I think the colours make the design stand out. I intend to experiment with the text.
Lighter colour makes the text stand out more.
