Scientists are making new studies of color and its effects on our health. They have known for a long time that the color of a room or the color of the light in it can affect our feelings and emotions. Many prisons and hospitals have at least one room that is painted pink. Officials have found that light and color can produce physical changes in our bodies.
Professor Falfan worked with a group of 9 disabled children at school in Albert. Two of the children were blind. The other seven had normal sight. The scientists changed the color of the school room, then looked for changes in blood pressure, heart beat and breathing rate. The effects of color changes were the same for the blind children as for those with normal sight. Their blood pressure dropped from about 120 to 100. Similar changes were reported in heart-beat and the breathing. The children also were calmer and less excited. Then the colors of the room were returned to orange and white. Blood pressure, heart-beat and breathing rate went up and the children became excited again.
Professor Falfan said different colors produce different levels of light energy. He said the differences seem to affect chemicals in the brain that carry messages from nerve to nerve and from nerve to muscle.

For many blind people, computers are inaccessible. It can cost $1,000 to purchase “screen reader” software, but two blind computer programmers from Australia have solved this problem.
Queensland University of Technology (QUT) graduate James Teh and business partner Michael Curran developed a free, open-source program, called NVDA, which provides a voice to read the words on a computer screen as the cursor(光标) moves over them. NVDA won the blind inventors an award in the grand final program of the ABC’s New Inventors, which aired on September 23. They took home the award for an invention that “might make a real difference to people’s lives or the environment.”
“A sighted person takes for granted that they can sit down at any computer and use it,” Mr Teh said. “We really are in the information age — everything is online these days. So access to computers for the blind is very important, which is why we wanted our software to be free.”
Mr Teh, who majored in software engineering at QUT, said blind students typically didn’t have the money to purchase “screen reader” technology, at the time in their life when they most needed it. Now NVDA could be downloaded on to anyone’s personal computer free of charge.
“It can also be copied to a USB stick, which can be used on any PC at school or university, with no installation required,” he said.
Mr Teh and Mr Curran have drawn on their own experience as blind computer users to develop a product which has some unique features. For example, as the mouse moves up and down the screen, a sound becomes higher and lower to let you know where the cursor is located.
NVDA has been translated into 27 languages, thanks to volunteer translators. To date, there have been over 50,000 downloads.
Mr Teh and Mr Curran have been working on the project since 2006. They worked on their product without any pay for two years. When Mozilla offered some funding in 2008, Mr Teh was able to quit his day job and work full-time developing NVDA.
