Using custom text color
Rename sub sprite in parent named 0x0000ee. If you want to change color of your text from blue to any other for example to RED then change the sprite name to 0xFF0000 or desired color.
But remember when you change it you will have to rechange three actions.
1.Action for submit button. Change the Tell Target to sprite you renamed.
2.Go into sprite up then sprite u and change the tell target to right path of sprite (you renamed).
3.Go into sprite down then sprite d and change the tell target to right path of sprite (you renamed).
