Internet safety

Internet safety

          Who know's the story about the big bad wolf, well the big bad wolf is on the Internet. The Internet can be a wonderful resource for kids. They can use it to research school reports, communicate with teachers and other kids, and play interactive games. Kids who are old enough to punch in a few letters on the keyboard can literally access the world.

But that access can also pose hazards. For example, an 8-year-old might do an online search for "Lego." But with just one missed keystroke, the word "Legs" is entered instead, and the child may be directed to a slew of websites with a focus on legs — some of which may contain pornographic material.

That's why it's important to be aware of what your kids see and hear on the Internet, who they meet, and what they share about themselves online.

Just like any safety issue, it's wise to talk with your kids about your concerns, take advantage of resources to protect them, and keep a close eye on their activities.

Internet Safety Laws

A federal law, the Children's Online Privacy Protection Act (COPPA), was created to help protect kids online. It's designed to keep anyone from obtaining a child's personal information without a parent knowing about it and agreeing to it first.

COPPA requires websites to explain their privacy policies on the site and get parental consent before collecting or using a child's personal information, such as a name, address, phone number, or Social Security number. The law also prohibits a site from requiring a child to provide more personal information than necessary to play a game or participate in a contest.

But even with this law, your kids' best online protection is you. By talking to them about potential online dangers and monitoring their computer use, you'll help them surf the Internet safely.

Bullies and mean girls have been around forever, but technology now gives them a whole new platform for their actions. The old "sticks and stones" saying is no longer true — both real-world and online name-calling can have serious emotional consequences for our kids and teens.

It's not always easy to know how and when to step in as a parent. For starters, most kids use technology differently than we do. They're playing games online and sending texts on their phones at an early age, and most teens have devices that keep them constantly connected to the Internet. Many are logged on to Facebook or Tumblr and chatting or texting all day. Even sending email or leaving a voicemail can seem old-school to them. Their knowledge of the digital world can be intimidating to parents.

But staying involved in kids' cyber world, just as in their real world, can help parents protect them from its dangers. As awareness of cyberbullying has grown, parents have learned more about how to deal with it. Here are some suggestions on what to do if this modern type of bullying has become part of your child's life.

Color theory

Basic Color Theory

Color theory encompasses a multitude of definitions, concepts and design applications - enough to fill several encyclopedias. However, there are three basic categories of color theory that are logical and useful : The color wheel, color harmony, and the context of how colors are used.

Color theories create a logical structure for color. For example, if we have an assortment of fruits and vegetables, we can organize them by color and place them on a circle that shows the colors in relation to each other.

The Color Wheel

A color circle, based on red, yellow and blue, is traditional in the field of art. Sir Isaac Newton developed the first circular diagram of colors in 1666. Since then, scientists and artists have studied and designed numerous variations of this concept. Differences of opinion about the validity of one format over another continue to provoke debate. In reality, any color circle or color wheel which presents a logically arranged sequence of pure hues has merit.

 

There are also definitions (or categories) of colors based on the color wheel. We begin with a 3-part color wheel.

 

Primary Colors: Red, yellow and blue
In traditional color theory (used in paint and pigments), primary colors are the 3 pigment colors that can not be mixed or formed by any combination of other colors. All other colors are derived from these 3 hues. 

Secondary Colors: Green, orange and purple
These are the colors formed by mixing the primary colors.

Tertiary Colors: Yellow-orange, red-orange, red-purple, blue-purple, blue-green & yellow-green
These are the colors formed by mixing a primary and a secondary color. That's why the hue is a two word name, such as blue-green, red-violet, and yellow-orange.

 Color Harmony

Harmony can be defined as a pleasing arrangement of parts, whether it be music, poetry, color, or even an ice cream sundae.

In visual experiences, harmony is something that is pleasing to the eye. It engages the viewer and it creates an inner sense of order, a balance in the visual experience. When something is not harmonious, it's either boring or chaotic. At one extreme is a visual experience that is so bland that the viewer is not engaged. The human brain will reject under-stimulating information. At the other extreme is a visual experience that is so overdone, so chaotic that the viewer can't stand to look at it. The human brain rejects what it can not organize, what it can not understand. The visual task requires that we present a logical structure. Color harmony delivers visual interest and a sense of order.

In summary, extreme unity leads to under-stimulation, extreme complexity leads to over-stimulation. Harmony is a dynamic equilibrium.

Some Formulas for Color Harmony

There are many theories for harmony. The following illustrations and descriptions present some basic formulas.

1. A color scheme based on analogous colors

 

Analogous colors are any three colors which are side by side on a 12 part color wheel, such as yellow-green, yellow, and yellow-orange. Usually one of the three colors predominates.
 

2. A color scheme based on complementary colors

 

Complementary colors are any two colors which are directly opposite each other, such as red and green and red-purple and yellow-green. In the illustration above, there are several variations of yellow-green in the leaves and several variations of red-purple in the orchid. These opposing colors create maximum contrast and maximum stability.

A color scheme based on nature

Nature provides a perfect departure point for color harmony. In the illustration above, red yellow and green create a harmonious design, regardless of whether this combination fits into a technical formula for color harmony.

Color Context

How color behaves in relation to other colors and shapes is a complex area of color theory. Compare the contrast effects of different color backgrounds for the same red square.

Red appears more brilliant against a black background and somewhat duller against the white background. In contrast with orange, the red appears lifeless; in contrast with blue-green, it exhibits brilliance. Notice that the red square appears larger on black than on other background colors.

Different readings of the same color

If your computer has sufficient color stability and gamma correction (link to Is Your Computer Color Blind?) you will see that the small purple rectangle on the left appears to have a red-purple tinge when compared to the small purple rectangle on the right. They are both the same color as seen in the illustration below. This demonstrates how three colors can be perceived as four colors.

Observing the effects colors have on each other is the starting point for understanding the relativity of color. The relationship of values, saturations and the warmth or coolness of respective hues can cause noticeable differences in our perception of color.
