LESSON 4.3

Color Theory & Opacity

+ info

In this lesson, students will explore color theory, color coding, and opacity inweb development. They will gain an understanding of the principles of color, learn how torepresent color in code, and consider accessibility and design principles related to color.

Objectives

In 1666, Issac Newton created the color wheel which is a tool to help understand color theory. The color wheel allows artists to see the relationships between different colors from different color groups. Primary colors, secondary colors, tertiary colors

History of Color Theory

Characteristics of Color Properties

Section I

Hues defines pure color with no addition of black or white. Saturation decreases the color gets more gray until it becomes fully desaturated. Lightness, also known as a color's value or brightness, is altered to create different tints and shades. Tints are made by adding white to a color and shades are made by adding black to a color. Color temperatures can be impacted based on surrounding colors. Neutral colors include colors like white, gray, brown, and black.

Color Properties

4 Color Schemes of Color Theory

BIt has the contrast that's lacking in monochromatic and analogous schemes while offering the balance that's harder to apply in complementary schemes.

Triadic

When using monochromatic color schemees it's important that the base color fits the overall mood of the design, and attention is paid to color psychology.

Monochromatic

Complementary colors typically have a lot of contrast between one another.

Complementary

The only unofficial rule that's typically applied when working with an analogous color scheme is to keep the palette colors within the same color temperature.

Analogous

Before virtual education, there was already distance education, for example, in the country, where people were educated via educational programs and materials, listening to classes on the radio and attending some meetings sometimes weekly, monthly or quarterly in accordance with the program.

A common but not always well understood characteristic is a contrast between the virtual and the real. This opposition does not allow for you to deeply think about virtual teaching. Virtual learning is still real because it uses the Internet or online media as a form of presence. In fact, the virtual represents the gateway to a more accentuated wealth in Distance Education (EAD).

Characteristics of the virtual and classic models

Methodologiesused

In virtual teaching

Section II

When we talk about methodologies we mean the "how" of teaching and this means that we think about how a person learns or, rather, the forms, and also the ways of teaching. This reflection is known as didactics and we have many examples, such as constructivist didactics that will emphasize peer learning and social environment and behavioral didactics that will emphasize the study of students' responses to different stimuli. These are just two examples, but there are different types of didactics. In the case of virtual teaching, learning and teaching also have their particularities.

A tip for online teachers is to take care of specific aspects that we mention and not to try to transpose or transfer the same practices from the classical teaching model, sometimes called the old teaching model, to the virtual teaching model.

A tip: be clear about your goals and aspirations..

That is, the dedication you must have, to do the readings, reflections...

essays, work and other proposed activities.

Virtual teaching assumes what some call maturity.

And for students, in addition to the responsibility of virtual learning, participation and interaction with teachers and other students will always be productive, because it will give you an idea of how things are going. from what people think and it will enrich the way you approach the topic you are studying and learning.

Myths related

to virtual teaching

Section III

Some are more famous than others, such as Greek myths, the creation myths of the world. The problem with myths is when they don't let us see beyond them. For example, suppose the myth that heavy objects fall faster than light objects remained true. Galileo would never have discovered the importance of gravity, and we would not be flying from one place to another so easily.

Myths are ways of understanding reality and are based on culture, feelings, prejudices, concepts, ideas, relationships, but that often do not take into account some facts and data that could enrich what they propose. Myths can be positive, when used to convey ideas and teachings. For example, many cultures have myths to explain how we understand ourselves as human beings.

The statistics show not only the current status of virtual education, but also its trends for the coming years. In fact, the total number of students in contact with virtual education is expected to be nearly $70 billion, more than three times the gross domestic product of the entire European Union.

A trend that emerges from the academic curriculum curve is the growing movement of free online course offerings. This type of course offers rich knowledge, the only difference is that some do not offer university-recognized certificates. Here you can see the best selling niches of online courses:
