Adjusting Hue and Saturation Dynamically

Tutorial 3 of 5

Introduction

In this tutorial, we will explore adjusting hue and saturation dynamically using SASS/SCSS. This is a powerful way to create dynamic color effects, making your web designs more engaging and visually appealing.

By the end of this tutorial, you'll learn:
- The basics of hue and saturation in CSS.
- How to use SASS/SCSS to adjust hue and saturation dynamically.
- How to create dynamic color effects.

Prerequisites:
- Basic knowledge of HTML and CSS.
- Basic understanding of SASS/SCSS.

Step-by-Step Guide

Hue and saturation are two of the primary properties that control how colors appear in CSS. Hue represents the type of color (red, green, blue, etc.), while saturation represents the intensity of that color.

In SASS/SCSS, we can adjust these properties with the adjust-hue and adjust-color functions, respectively.

Example

$base-color: #6b717f;

.adjusted-color {
  color: adjust-hue($base-color, 45deg); // Adjusts the hue of the base color by 45 degrees.
}

In this example, the adjust-hue function takes two arguments: the original color and the amount by which to adjust the hue. The result is a new color.

Code Examples

Let's look at some practical examples.

Example 1: Adjusting Hue

$base-color: #6b717f;

.new-color {
  color: adjust-hue($base-color, 45deg);
}

In this example, adjust-hue modifies the hue of $base-color by 45 degrees. The new color is assigned to the .new-color class.

Example 2: Adjusting Saturation

$base-color: #6b717f;

.new-color {
  color: saturate($base-color, 20%);
}

Here, saturate increases the saturation of $base-color by 20%. The resulting color is more vibrant than the original.

Summary

In this tutorial, we have learned how to adjust hue and saturation dynamically in SASS/SCSS. We've seen how these adjustments can be used to create dynamic color effects.

Next step could be learning about other color functions in SASS/SCSS like lighten, darken, desaturate, etc.

Practice Exercises

Exercise 1: Adjust Hue

Create a SASS script that adjusts the hue of a color by 90 degrees.

Solution

$base-color: #6b717f;

.new-color {
  color: adjust-hue($base-color, 90deg);
}

Exercise 2: Adjust Saturation

Create a SASS script that reduces the saturation of a color by 30%.

Solution

$base-color: #6b717f;

.new-color {
  color: desaturate($base-color, 30%);
}

In both exercises, replace #6b717f with any color of your choice and observe the changes.

Remember, the best way to learn is by doing. So, keep practicing!
