This time we talk about another important subject in watercolour paintings, since watercolour is one of the popular mediums compared to any other materials we used in paintings. Anyway, there are many types of watercolour, and we might want to know what are their differences and which one to use.

They are cheaper types of watercolours and there is also an artist grade that can cost more expensive. What are their differences? Watercolour is made cheaper for the student grade so it will be more affordable for students to learn. This is possible by changing its ratios of their main ingredients that consist of pigment, gum Arabic, additives and solvent. So, the student grade is totally for practicing only, when we want to be a professional painter, we need to use the artist grade watercolour for a few reasons.

Besides their qualities, artist grade watercolour not only have a brighter coloured pigments, but they also blended carefully to have a good texture. Professional artist has different preferences for the texture quality, anyway, this high grade watercolour has far better texture (evenly) than student grade watercolour. Other than easy to apply, watercolour must have the transparent quality as one of the main characters for watercolour that differentiate between watercolours than any other painting techniques.

The artist grade watercolour is more lightfast; the quality of the pigment not prone to discolour when exposed to light. This is very important to make sure the painting can be kept for a longer period of time (and increase their value). The lightfast value, usually provided by the watercolour manufacturer in their product’s specification (or you need to contact them to know about the details).

Then they are a few different types of watercolour (basically on their packaging). Some of them are coming in tubes while some of them come in pan. Both of them have good quality of pigments, but it’s totally depend on how you use your colours. If you don’t want your colours mixed with each other, then a tube is easier to handle. Anyway, for travelling purposes, pan is always easier.

The new types of watercolour also known as liquid watercolour is ready to use types. Mostly they have a brighter colour, but can also be diluted to produce paler hues. This watercolour is suitable for traditional brush or an airbrush technique. Usually it will be used together with traditional watercolour as a mixed media (to give contrast in the painting).

Watercolour Sets

Watercolours are sold in sets of 6 colours up to 36 colours, you might want to know which set to choose. Since colours are produced from three primary colours (Red, Yellow and Blue). You just need to make sure, you have this three main colours first. Then you also might need to have white and black because they cannot be produced by those three colours. Having a bigger set of colours will speed up your painting process, and also producing consistent quality of the colour.

It is important to know more about the materials that you use for your paintings. Especially when you think about to sell it to your customers. Good paintings should have durability for storage (this will increase their value), and might be useful as future reference. It’s Okay to have different quality of paints for practicing purposes and for the real paintings.

Freshwater Aquarium Fish - Discus

Multiple colours of discus in aquarium.

Symphysodon or more popular known as discus is one of the most popular aquarium freshwater fish for since long time ago. This explained why there are so many varieties of discus in the market to make sure there always new characteristic introduce into the market every year. Discus originally native to Amazon River basin is actually part of cichlids genus. Today most of the fish breed and live in the aquarium.

Not like gourami that little tougher to water condition and diseases, discus is more sensitive and considered as ‘fragile’ fish. It’s not suitable for starting your aquarium hobby – unless you already started with few other easier to keep fishes for some period of times. Anyway for some qualities this fish has, you might want to try to keep it in your aquarium at some points.

Wide varieties of colours and patterns.

Gathering in groups.

There are three main species of discus; Symphysodon aequifasciatus (blue), Symphysodon discus (red), and Symphysodon tarzoo (green). Anyway by selective breeding, aquarist successfully produced many varieties of colours for this fish. So there are many beautiful discus fish you can keep - if you like to see all of these beautiful colourations and patterns.

As any other cichlids discus has thinner body from the top, but flatter and beautifully almost round from the side. This shapes rarely found in freshwater fish, that’s another reasons why discus become so popular. Discus also has patterns on its scales. As mentioned before, they are many new patterns produce by aquarist all over the year.

Discus behaviour itself is wonderful to watch. It’s highly social behaviour and prefer to be in groups up to dozens of individuals and only separate itself from the group during the breeding season. Discus will take care their young for the first four weeks. They also will secrete a mucus for their young to feed on. For all that reasons, discus still maintain itself as popular aquarium fish for so many years.
