|-
|| '''Slide 1'''

'''Title Slide'''
|| Welcome to this spoken tutorial on '''Defining Colours and Environments'''.
|-
|| '''Slide 2'''

'''Learning Objectives'''
|| In this tutorial, we will learn to:
* Create boxes with colours and borders
* Define custom colors using '''RGB''', '''CMYK''', '''HTML''', and other models and
* Apply colours to table rows
|-
|| '''Slide 3'''

'''System Requirements'''

To record this tutorial, I am using:
* '''Linux Mint OS version 21.3'''
* '''TeXworks version 0.6.6'''
|| To record this tutorial I’m using the following setup.
|-
|| '''Slide 4'''

'''Pre-requisites'''
|| To follow this tutorial, learners should have basic knowledge of''' LaTeX'''.
|-
|| '''Slide 5'''

'''Code files'''

The following code file is required to practice this tutorial:

1. '''xcolor-eg.tex'''

This file is provided in the Code Files link of this tutorial page.
|| The following code file is required to practice this tutorial.

|-
||
|| Let us get started.

Let us see how to get a framed box with colours.
|-
|| Uncomment the line 27

Run the code

show the output
|| Uncomment line 27.

Run the code.

Output shows a boxed text in yellow and some random text in it.
|-
|| '''Highlight: '''

'''line 27'''
|| The command '''\colorbox '''takes 2 arguments.

The first one is the colour of the box.

And the second one is the text that is inside the box.
|-
|| Uncomment the line 31

Run the code

show the output
|| Uncomment line 31.

Run the code.

Output shows some text enclosed in a box.

The color of the frame is red and

box filled with green colour.
|-
|| '''Highlight:'''

'''line 31'''
|| This command creates a framed box.

The command '''\fcolorbox '''takes 3 arguments.

First one is the frame colour.

Second one is the colour to be filled in the box.

Third is the actual text that goes inside the framed box.
|-
|| Uncomment the line 33

Run the code

show the output
|| Uncomment line 33.

Run the code

Output shows another framed box with a black frame filled with lime colour.
|-
||
|| Let us now see how to define new colours.
|-
|| Uncomment the line 35

'''Highlight:'''

'''line 35'''

Point to the defined colour.

Show the options shown as reference,
|| Uncomment line 35.

The command '''\definecolor''' defines a new colour.

It takes 3 arguments.

1. name of the new colour to be defined

2. model – '''rgb, cmyk''' etc.

3. colour definition – Each number shows how much red, green, and blue are mixed to get a new color.

Here we have defined a colour called '''myOrange''' in rgb model .

Complete options are given at the end of the '''TeX''' file for reference.
|-
||
|| Let us apply the newly defined '''myOrange '''colour to the text.
|-
|| Uncomment the line 37

Run the code and show the output
|| Uncomment line 37

Run the code

Output shows the text in '''myOrange''' colour from the section heading onwards.
|-
||
|| Let’s see how to colour the rows in the table.
|-
|| Comment line 4

Uncomment the line 41, 5

Run the code and show the output
|| Comment line 4.

Uncomment lines 5 and 41.

Run the code.

The output shows the table rows in yellow and lime colour.
|-
|| '''Highlight:'''

'''lines 41, 5'''
|| The command '''\rowcolors''' painted the rows in the table.

We also need to load the package''' xcolor''' with''' [table]''' option to use this command.

The '''\rowcolors''' command takes 3 arguments:

1. The row number from which coloring should begin

2. color for odd-numbered rows

3. color for even-numbered rows

Here, it starts colouring from row 1.

Odd rows are colored in yellow and even rows in lime colour.
|-
|| Point to the table.
|| Let us see how changing the starting row number affects the coloring.
|-
|| Comment the line 41

Uncomment the line 43

Run the code and show the output
|| Comment line 41

Uncomment line 43.

Run the code.

Output shows colouring of the rows starting from the second row.
|-
|| Highlight line 43
|| Here the''' \rowcolors '''command is defined with argument 2.

This means the coloring starts from row two.

The first row is not coloured.
|-
|| '''Slide 6'''

'''Summary'''

In this tutorial, we have learnt:
* Creating boxes with colours and borders
* Defining custom colors using RGB, CMYK, HTML, and other models
* Applying colours to table rows
|| With this we come to the end of this tutorial.

Let us summarise.
|-
|| '''Slide 7'''

'''Assignment'''
|| As an assignment,

Define a new colour maroon using the '''RGB''' model mixing as (0.9, 0, 0).
