Did you know the colour blue has shown to slow heart rate and breathing, making you physically calmer? It is known to reduce respiratory rhythm and encourage mental activity, introspection, concentration and focus inwards. It is believed to be a good colour to aid in meditation or relaxation. It is also a colour that suggests peace. It is the colour of the clear sky and calm sea, both of which are linked to inner serenity, calm and clarity.

Did you know that yellow has a dark side to it and is the colour of caution and physical illnesses like jaundice, malaria and pestilence? Egoism, cowardice, betrayal and madness are the traits associated with yellow. It is no coincidence that the sources of yellow pigments are toxic metals such as cadmium, lead, chrome and urine.

Have you ever wondered why there are blue stars, yellow stars, red stars, but no green stars?  As it turns out, there are green stars, that is, stars that radiate much of their light in the green part of the spectrum.  However, the total combination of the full range of colours of a 'green' star appears white to the human eye.  If you pass the colour from a whitish star through a prism, you will be able to see all the colours, including green, spread out in a continuum.

Painting edges can be a tricky affair. It helps to know the tricks of the trade on how to go about it. Wiggling the brush a little bit can help the paint release into tight corners. It is also a wonderful technique to fill in missed areas as you make a second pass. However, remember not to wiggle the brush too hard. Just a little vibration is all that is needed to get the perfect results.

When you are satisfied with the cut-in line while painting, apply a neater finish for a smooth look by feathering or thinning the edge. It is a simple technique wherein without reloading the brush, you need to drag the tips of the bristles lightly over the outside edge to spread the paint in a thin layer and get rid of excess build-up and any ridges present. This feathering step guarantees that the cut-in line does not show up as a stripe after rolling the walls.

Painting a room is one of the quickest and easiest ways to give your home a new life. While DIY home projects can be a lot of fun, you would also want it to be as successful as possible. We bet you didn't know that there was a technique when it comes to dipping the paintbrush into the paint can? Plunging your brush too far into the paint is a wrong way to go about it. Dip it only a third of the way in. This way you will get enough paint on your brush without wasting or pushing the paint deep into the bristles, which is difficult to clean later. Remember this the next time you start a DIY project to save yourself some trouble.
