The color white, as represented in the description of the Great White Throne, carries profound significance. In Scripture, white symbolizes purity and cleanliness, as seen in Psalm 51:7, where David pleads to be washed and made whiter than snow, reflecting a desire for spiritual cleansing. This imagery ties white to a state of being untainted by sin, representing a character that is pure and dazzling in its righteousness. Similarly, in Ecclesiastes 9:7-8, white garments are linked with joy and acceptance by God, indicating that purity and righteousness bring happiness and fulfillment. In Revelation 1:14, Christ's head and hair are described as white like wool, as white as snow, emphasizing His absolute purity. This theme continues in Revelation 19:11 and 14, where Christ and His armies are associated with white horses and fine linen, clean and bright, underscoring their righteousness and separation from worldly stain. Revelation 19:7-8 further confirms that the fine linen represents the righteous acts of the saints. Applied to the Great White Throne, the color white signifies that the Judge who sits upon it is holy, righteous, and pure. His decisions during the judgment are unerring and just, ensuring that those who stand before Him can trust in the perfection of His rulings without fear of unfairness.

In the context of the white horse and its rider from Revelation 6:1-2, symbolizing religious communication and deception, the color white carries significant symbolic weight. Biblically, white often suggests purity, righteousness, holiness, glory, victory, and perfection. This positive connotation is evident in various scriptures, such as Ecclesiastes 9:8, where Solomon advises, "Let your garments always be white," interpreted as reflecting the joy, purity, and beauty of a righteous individual. Similarly, the Shulamite describes her Beloved, a type of Christ, as white in Song of Songs 5:10, implying His spotless and holy character. Daniel also envisions the Ancient of Days in a garment white as snow with hair like pure wool in Daniel 7:9, echoing John's portrayal of the glorified Christ in Revelation 1:13-16. In Revelation itself, white predominantly holds a positive meaning, often associated with God, Christ, glorified saints, or objects like the Great White Throne. However, this seemingly virtuous facade of white in the imagery of the white horseman is deceptive, concealing a deadly and unholy purpose as he goes out conquering with a bow, spreading counterfeit truths and false gospels.

In the vision of Revelation, the martyred saints under the altar are each given a white robe as a symbol of their salvation. The significance lies in the color white, representing purity, righteousness, joy, victory, and perfection. This white robe, whether formal or common, underscores the spiritual state of these faithful Christians who have endured persecution and martyrdom.

In the exploration of God's perspective on outward appearance, the symbolism of white as a representation of purity and righteousness is a recurring theme throughout the scriptures. In Revelation 3:17-19, Jesus counsels the deceived church to purchase white raiment from Him to clothe themselves, covering the shame of their spiritual nakedness and reflecting a call to repentance and true richness in spirit. This imagery underscores the need for attire that aligns with God's standards of righteousness. Further, in Revelation 19:7-9, the Bride of Christ is depicted as arrayed in fine linen, clean and white, symbolizing the righteousness of the saints. This radiant linen represents the upright living, deeds, and right standing with God of His holy people, emphasizing the importance of being appropriately dressed for the marriage supper of the Lamb. Additionally, in Exodus 28:39-43, the garments for Aaron's sons, as priests ministering in the holy place, are made of fine linen, described as stunningly white in Jewish commentaries. This white attire reflects dignity and honor, setting God's people apart and sanctifying them as they come into His presence, highlighting the connection between clothing and spiritual status. The consistent use of white in these contexts illustrates God's expectation for His children to dress in a manner that mirrors their inner transformation and respect for His holiness. It serves as a visible testament to their identity as His representatives, aligning their outward appearance with the purity and righteousness He desires.

In the context of cleansing and purification, the Bible frequently references water as a fundamental agent, both physically and symbolically. Water, recognized as the base for most cleaning solutions, embodies purity and is paralleled in spiritual rituals. A significant aspect of this symbolism is seen in the color white, often associated with purity and cleanliness. Just as water traps and retains dirt, rendering it clean, the imagery of white reflects an unblemished state, mirroring the spiritual cleansing intended through rituals like the footwashing ceremony instituted by Jesus Christ. His act of washing the disciples' feet with water emphasized a profound purification, not merely physical but deeply spiritual, aligning with the symbolic essence of white as purity. This representation underscores the ultimate cleansing power that makes us acceptable before God, akin to the pristine nature of white.
