It says preferred orb. This means the Pokemon is more likely to appear in the pink/orange/blue orb. U don’t have to have plenty orbs of the colours since you can’t collect orbs. As you encounter each of the Therian form Pokemon, a new color of orb is unlocked. All after Tornadus, green orbs appear. Orange orbs appear after Thundurus, and blue unlock after Landorus. The orbs themselves transition between the colors, so to get a color, you have to hit the orb when it’s that color.

Hope this helped
