**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 meand the gradual change of a variable. So, **Delta E** represents changes in sensation.

You can measure Delta E on a scale from 0 to 100. 0 meaning less color difference and 100 full distortion. Perception ranges explained by **Zachary Schuessler **are Shown below:

**<= 1.0:**Imperceptible to 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.

The sample dataset showcases Terms, Reference Value, and Measured Value.

**L, a,** and** b **represent** three** axes of color.

**L**represents**darkness**(**0**) to**lightness**(**100**).**a**means shades of greenness**(-128)**to redness**(+127)**.**b**means shades of blueness**(-128)**to yellowness**(+127)**.

### Method 1 – Using a Generic Formula to Compute Delta E Color

**Steps:**

- Select a blank cell
**D9**to keep Delta E Color. - Enter this formula in
**D9**.

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

- Press
**ENTER**to see the result.

### Method 2 – Using the Excel SQRT Function for Delta E Color Calculation

**Steps:**

- Select a blank cell
**D9**to keep Delta E Color. - Enter this formula in
**D9**.

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

The **SQRT** function will return the square root of the summation of three terms (the square of subtraction from reference value to measured value).

- Press
**ENTER**. - This is the output.

### Method 3 – Merge the SQRT & POWER Functions to Calculate Delta E

**Steps:**

- Select a blank cell
**D9**to keep Delta E Color. - Enter this formula in
**D9**.

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

**Formula Breakdown**

- The
**POWER**function will return the output of a number raised to a specified power. **POWER(C7-D7,2)—>**the**subtraction**of a measured value**(D7)**from the reference value**(C7)**is**base, 2**is the specified**power.****Output: 19.4481.****POWER(C6-D6,2)—>**returns**16.8921.****POWER(C5-D5,2)—>**turns**23.2324.**- The
**Plus sign (+)**adds the**three**outputs.**Output: 59.5726.**

- The
**SQRT**function returns the square root.

- Press
**ENTER.** - This is the output.

### Method 4 – Combining the SQRT & SUMSQ Functions to Find Delta E Color

**Steps:**

- Select a blank cell
**D9**to keep Delta E Color. - Enter this formula in
**D9**.

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

**Formula Breakdown**

- The
**SUMSQ**function returns the summation of the square of three terms (the subtraction from the reference value to the measured value). **SUMSQ(C5-D5,C6-D6,C7-D7)—>**returns**59.5726.**- The
**SQRT**function returns the**square root**.

- Press
**ENTER**to see the result.

Very helpful, and big thank you for the excel sheet.

I use to give an free program to my students,taking from a printing company that gives the small program for free.

But this is more helpful.

Thanks from Portugal
