Answer

For Jain chanting and meditation, the commonly understood colors are:

• ॐ / Om — usually visualized as white or golden, representing purity, divinity, and spiritual elevation.
• ह्रीं / Hreem — often associated with golden, red, or radiant light, depending on the tradition and mantra practice.
• श्रीं / Shreem — commonly associated with golden or bright yellow, symbolizing auspiciousness, prosperity, and positive spiritual energy.

Explanation

In Jain Dharma, the power of chanting comes mainly from:

• purity of intention,
• right faith,
• concentration,
• devotion toward Arihant, Siddha, Acharya, Upadhyay, and Sadhu,
• and inner detachment.

Colors may be used as a helpful support for concentration, but they are not the main essence of the mantra.

Spiritual Understanding

If you are chanting these sounds in a Jain devotional or meditative way, keep the mind calm, pure, and non-violent. Visualizing peaceful white, golden, or radiant light can help focus the mind, but the true goal is purification of the soul.

Takeaway

You may visualize:

• Om as white or golden,
• Hreem as golden/red radiant light,
• Shreem as golden/yellow light.

But the most important “color” is the inner purity of the soul.
