**What Is Delta E?**

Here, **E** represents **“Empfindung”.** Actually, **Empfindung** is a **German** word that means sensation. On the other hand, **Delta** is a **Greek** word that denotes the gradual change of a variable. So, this **Delta E** represents changes in sensation.

Basically, you can measure **Delta E** on a scale from **0 to 100. **Where 0 denotes less color difference. On the other hand, **100** means full distortion. Moreover, the usual perception ranges explained by **Zachary Schuessler **are given below:

**<= 1.0:**Not sensible by the human eye.**1-2:**distinguishable through close attention.**2-10:**Perceptible at first sight.**11-49:**Colors are comparable to the opposite.**100:**Colors are definitely the opposite.

## 4 Methods to Calculate Delta E Color in Excel

Here, I will demonstrate** four** suitable methods with detailed steps on how to calculate **Delta E Color** in Excel. For your better understanding, I am going to use the following dataset. Which contains **three** columns. These are** Terms**, **Reference Value**, and **Measured Value**. The dataset is given below.

Actually, the three terms **L, a,** and** b **represent** three** axes for color difference.

- Where
**L**denotes**darkness**(**0**as the initial value) to**lightness**(**100**as the last value). - Then,
**a**means the shades of greenness**(-128)**to redness**(+127)**. - On the other hand,
**b**denotes the shades of blueness**(-128)**to yellowness**(+127)**.

### 1. Use Generic Formula to Compute Delta E Color

You can use a generic formula to calculate **Delta E Color** in Excel. Now, follow the steps given below.

**Steps:**

- Firstly, you must select a blank cell
**D9**where you want to keep the**Delta E Color**. - Secondly, you should use the formula given below in the
**D9**cell.

`=((C5-D5)^2+(C6-D6)^2+(C7-D7)^2)^(1/2)`

Actually, this is a simple algebraic formula. I have used some basic operations like **subtraction**, **summation**, and **power**.

- Then, press
**ENTER**to get the result. - Finally, you will get the
**Delta E Color.**

### 2. Employ Excel SQRT Function for Color Calculation of Delta E

Here, I will use **the SQRT function** to calculate **Delta E Color** in Excel. Basically, I’m going to use just a modified version of the previous formula. So, follow the steps given below.

**Steps:**

- Firstly, you must select a blank cell
**D9**where you want to keep the**Delta E Color**. - Secondly, you should use the formula given below in the
**D9**cell.

`=SQRT((C5-D5)^2+(C6-D6)^2+(C7-D7)^2)`

Here, in this formula, the **SQRT** function will return the **square root **of the summation of **three** terms. Where these** three** terms are the** square** of subtraction from **reference **value to **measured** value.

- Consequently, press
**ENTER**. - As a result, you will get the
**Delta E Color**.

### 3. Merge SQRT & POWER Functions to Calculate Delta E

Now, I will use **the POWER function** along with the **SQRT** function to calculate **Delta E Color** in Excel. Actually, this is the more updated version of the previous formulas. Let’s follow the steps given below.

**Steps:**

- Firstly, you must select a blank cell
**D9**where you want to keep the**Delta E Color**. - Secondly, you should use the formula given below in the
**D9**cell.

`=SQRT(POWER(C5-D5,2)+POWER(C6-D6,2)+POWER(C7-D7,2))`

**Formula Breakdown**

- Here, in this formula, the
**POWER**function will return the output of a number raised to a specified power. - First,
**POWER(C7-D7,2)—>**here the**subtraction**of measured value**(D7)**from the reference value**(C7)**is**base, 2**is that specified**power.** **Output: 19.4481.**- Similarly,
**POWER(C6-D6,2)—>**gives**16.8921.** - Then,
**POWER(C5-D5,2)—>**turns**23.2324.** - After that, the
**Plus sign (+)**will add all**three**outputs.**Output: 59.5726.**

- Finally, the
**SQRT**function will return the square root of the above output.

- Consequently, press
**ENTER.** - Lastly, you will see the
**Delta E Color.**

### 4. Combine SQRT & SUMSQ Functions to Find Delta E Color

Here, I will use a **combination** of **SQRT** and **SUMSQ** functions to calculate the **Delta E Color** in Excel. So, follow the steps given below.

**Steps:**

- Firstly, you must select a blank cell
**D9**where you want to keep the**Delta E Color**. - Secondly, you should use the formula given below in the
**D9**cell.

`=SQRT(SUMSQ(C5-D5,C6-D6,C7-D7))`

**Formula Breakdown**

- Here, in this formula, the
**SUMSQ**function will return the summation of the square of**three**terms. - Where these
**three**terms are the subtraction from the**reference**value to the**measured**value. - So,
**SUMSQ(C5-D5,C6-D6,C7-D7)—>**returns**59.5726.** - Then, the
**SQRT**function will return the**square root**of that output.

- Subsequently, press
**ENTER**to get the result. - As a result, you will get the
**Delta E Color**.
