Hi Digit4l. Glad that you like our game.
Only evolvable cards can be selected. If the whole bar is darkened and cannot be selected, that means this card has reached its max star rarity level and cannot be evolved further.
The whole bar of evolvable cards with sufficient materials will be lightened.
The card profile picture of the evolvable cards without sufficient materials will be darkened. But you can still select them to check what materials are missing.
Enjoy the game!
