Colors used in Panch Parameshti Dhyan (prayers) are five:

• White
• Red
• Yellow
• Blue
• Black

They correspond to the five Panch Parmeshthi:

• Arihant (white)
• Siddha (red)
• Acharya (yellow)
• Upadhyay (blue)
• Sadhu (black)

Different Jain traditions may describe or emphasize these associations slightly differently, but the above mapping is a common convention in many practice texts.
