Isaiah’s Color-Vivid Invitation
Isaiah opens his book with a shocking picture: God’s people have broken covenant, their rituals are empty, and their hands are stained with blood. Then, in one of the most hopeful verses in all scripture, God invites them:
“Though your sins be as scarlet, they shall be as white as snow; though they be red like crimson, they shall be as wool” (Isaiah 1:18).
It’s more than poetry. For Isaiah’s audience, these colors were drawn from everyday life, yet carried layers of social, economic, and religious meaning. When we see how Isaiah used them, we understand not only his warning but also the astonishing promise of God’s mercy.
Why Colors Matter in Anthropology
Anthropologists Brent Berlin and Paul Kay discovered that languages don’t develop words for colors randomly. They grow in a pattern. The earliest terms always begin with light and dark (white and black). The next is always red. Only later do languages add terms like yellow, green, blue, brown, purple, and so on. Later, Kay and Luisa Maffi refined this into partitions:
Every language begins by splitting the world into light vs. dark.
Then comes red, the most striking hue—blood, fire, life.
Later, the warm–cool divide emerges: yellows and greens versus blues.
What this means is that white and red are the most universal, primal colors for human meaning-making. Isaiah knew this instinctively. He drew on the two most basic anchors of the human color world to paint a picture of sin and cleansing that no one could miss.
The World Behind Isaiah’s Words
To Isaiah’s audience, scarlet and crimson weren’t generic reds. They were the richest, most stubborn dyes known in the ancient Near East. Made from tiny insects painstakingly harvested and crushed, scarlet was costly and permanent. Once it bonded to fabric, no ordinary washing could remove it.
White, on the other hand, wasn’t the natural state of cloth. Wool came off sheep cream or grayish. To make it bright white, fullers labored with alkaline soaps, running water, and the sun. Everyone in Jerusalem knew the Fuller’s Field, a landmark where laundry was beaten, washed, and dried.
So when Isaiah spoke of scarlet sins and white wool, he wasn’t being abstract. He was pointing to what people saw in their daily lives: dyes that could not be undone, and wool that only skilled hands could whiten. The audience knew what he meant: sin is like a dye that never comes out. And they knew why the promise was radical: God says He can do what no human craft can accomplish.
The Symbolism of Red and White
Red (Scarlet/Crimson): In Israelite thought, red was tied to blood. Blood meant life (Leviticus 17:11), but also guilt and violence when shed wrongly. Red could symbolize vitality or judgment. Here it is unmistakably guilt.
White (Snow/Wool): White meant purity, holiness, and cleanness before God. Priestly garments were white linen. White was the visible sign of being ritually clean, fit for God’s presence.
Isaiah’s pairing is brilliant: he uses the earliest and strongest color anchors in human perception, red and white, to show the difference between guilt and forgiveness, sin and purity, rebellion and renewal.
Covenant Mercy in Living Color
Isaiah’s chapter is a covenant lawsuit. God is prosecuting His people for breach of contract. And yet, in the middle of judgment, He extends an offer: “Come, let us reason together.” This is covenant language. The Great King, who has every right to condemn, offers instead reconciliation.
The use of scarlet and white makes the offer unforgettable. It’s as though God is saying: Even if your guilt is as deep as the richest dye, I can bleach it away. Even if you feel permanently marked, I can remake you.
How the Book of Mormon Carries This Forward
The Book of Mormon picks up Isaiah’s colors and frames them around Christ’s atonement. Alma asks, “Have your garments been cleansed and made white through the blood of Christ?” (Alma 5:21). Here the paradox becomes even sharper: it is red blood that makes white purity possible. Nephi and Moroni both use the image of white garments as symbols of being made pure through Christ (2 Nephi 2:22; Moroni 7:48).
The Book of Mormon shows that Isaiah’s promise finds its fulfillment in Jesus Christ. He alone can do the impossible: reverse scarlet into snow.
Insights for Today
Isaiah speaks in everyday images. His people knew dyes and fullers’ work. God speaks to us in the same way through what we see and know.
Sin feels permanent. Like scarlet dye, our mistakes can seem fixed and unchangeable.
God does the impossible. His covenant mercy is not limited by what humans can do. He offers cleansing beyond our reach.
Christ fulfills the promise. The Book of Mormon testifies that His blood is what whitens our garments, making Isaiah’s words real in every life.
Conclusion
Isaiah 1:18 is beautiful poetry. And it is anthropology, theology, and covenant hope woven together. By using the most basic, universal colors of human perception, red and white, Isaiah paints the drama of sin and salvation in a way that every person can feel. For ancient Judah, it meant that even sins dyed scarlet could be made white by the LORD’s cleansing. For disciples today, it means that Jesus Christ can take what seems most permanent in our failures and transform it into purity.
Scarlet to snow. Crimson to wool. This is the gospel in color.
