29. HEX vs RGB vs HSL, What It Means for This Color

As a writer, I work with graphic designers in a creative agency. This strange breed of homo sapiens speak in their own, special language. Their language is Pantone swatches and their idea of fun is arguing about color theory. They mutter in codes like #fc94af. A set of numbers like RGB. Or something called HSL.

I have grasped some understanding over the years. Now I see color like they do, especially for shades like #fc94af that sit between pink and peach.

Why Colors Have Different Formats

Think of HEX, RGB, and HSL as different ways to describe the same thing.

Like describing a person by:

• Name

• Height and weight

• Personality

Same person. Different perspectives.

What Is HEX?

HEX is the format you see most often online.

Example

#fc94af

What It Means

It’s a combination of numbers and letters that represent:

• Red

• Green

• Blue

Each pair controls how much of each color is used.

Simple Way to Think About It

HEX is like a color ID.

It’s:

• Precise

• Fixed

• Easy to copy

What It Tells Us About #fc94af

• High red value

• Medium green

• Slightly higher blue

This mix is why it feels:

• Soft

• Warm

• Slightly pink-peach

What Is RGB?

RGB stands for:

• Red

• Green

• Blue

Example

#fc94af in RGB looks like:

• Red: 252

• Green: 148

• Blue: 175

What It Means

Each number controls how strong that color is. Higher number = more intensity.

Simple Way to Think About It

RGB is like a recipe.

It tells you:

• How much red

• How much green

• How much blue

Why This Matters

Looking at the values:

• Red is very high

• Green is moderate

• Blue is slightly higher than green

Result

This creates a color that:

• Leans warm because of red

• Feels soft because the values are balanced

• Sits between pink and peach

What Is HSL?

HSL stands for:

• Hue

• Saturation

• Lightness

Example (Simplified)

#fc94af in HSL is roughly:

• Hue: around 340°

• Saturation: high

• Lightness: fairly light

What Each Part Means

Hue

This is the “type” of color.

• 0° = red

• 30° = orange

• 340° = near pink

Saturation

This is how strong or muted the color is.

• High = vivid

• Low = dull

Lightness

This controls how light or dark the color is.

• Higher = softer, lighter

• Lower = deeper, darker

Simple Way to Think About It

HSL is how humans naturally understand color.

It describes:

• What color it is

• How strong it is

• How light it feels

Why HSL Explains #fc94af Best

HEX and RGB tell you the structure. HSL tells you the feeling.

For #fc94af

• Hue sits between red and pink

• Lightness makes it soft

• Saturation keeps it clear but not harsh

Result

A color that feels:

• Warm

• Gentle

• Slightly shifting

Why This Color Feels Like Two Colors

Now we connect everything.

From RGB

High red makes it warm.

From HSL

Hue sits near pink but close to peach territory.

From Lightness

The softness allows it to shift depending on light.

Final Effect

It can look:

• Pink in cooler light

• Peach in warmer light

Why HEX Alone Isn’t Enough

HEX is precise. But it doesn’t explain behavior.

It Tells You

“What the color is”

It Doesn’t Tell You

“How the color feels”

That’s Why People Get Confused

Two people see #fc94af and say different things. HEX is fixed. Perception is not.

Why RGB Helps Designers

RGB is useful when you want control.

You Can Adjust

• Add more red → warmer

• Add more blue → cooler

For Example

If you want #fc94af to feel more peach:

• Increase green slightly

If you want it more pink:

• Increase red or blue balance

Why HSL Is Best for Everyday Use

If you’re not designing professionally, HSL is easier to think with.

You Can Adjust Feel Directly

• Want softer → increase lightness

• Want more muted → reduce saturation

• Want more peach → shift hue slightly toward orange

It Matches How You Think

You’re not thinking in numbers.

You’re thinking:

• Warmer

• Softer

• Brighter

Real-Life Example: Changing the Same Color

Let’s say you start with #fc94af.

Scenario 1: More Pink

• Slightly shift hue toward red

• Keep lightness high

Scenario 2: More Peach

• Shift hue toward orange

• Add a bit more warmth

Scenario 3: More Neutral

• Reduce saturation

• Keep lightness soft

Result

Same base color. Different feel.

Why This Matters for Interiors

If you’re using this color in your home, these formats help you understand how it behaves.

With Warm Lighting

• Looks more peach

• Feels cozy

With Cool Lighting

• Looks more pink

• Feels fresher

With Neutral Surroundings

• Looks balanced

Why This Matters for Fashion

The same idea applies to clothing.

On Skin Tone

• Warm skin → color leans peach

• Cool skin → color leans pink

In Different Lighting

• Daylight → brighter

• Indoor light → warmer

HEX, RGB, and HSL are not competing systems. They are different ways of understanding the same color.

HEX

• Fixed identity

RGB

• Structure and balance

HSL

• Feel and behavior

When you see a color like #fc94af, you’re not just looking at numbers.

You’re seeing a mix of:

• Light

• Context

• Perception

HEX tells you what it is. RGB tells you how it’s built. HSL tells you why it feels the way it does. And once you understand that, colors stop feeling confusing. They start feeling flexible.

And a lot more interesting.
