colour theory part 2

Natural colours are produced by primary and secondary colours mixing together to make a chromatic value of 0.

We don't see pure colours, its based on chromatic values:

-Juxtaposition, balancing lights and darks with the colours.

-tonal perception, high and low contrast.

-Weight, colours do have weight which we see visual.

The amount of any colour effects how we see colour, for example, the slide we saw had yellow and violet which changed the way we viewed both colours depending on intensity of stripes of both colours. we either see yellow more but if a lot of purple strips were placed over the yellow strips, it will hurt our eyes.

There are temperatures to colours, like cool and warm. we can produce really interesting effects by controlling the temperatures such as making warm shades and cool highlights. colours can control what happens when different colours can make gradients from temperatures of cool and warm colours.

There are a lot of ways to mess with colours and produce interesting concepts which allows us experiment on how colours are applied to objects in a scene, also what is needed to change a colour by placing another colour besides it.

one example from my experience is giving an extra shade which is the opposite tertiary and this add a highlight which either can be cool or warm. Most of the time manipulating colours to make it look like another colour is difficult. By doing so you can add colours which dont belong with the colour. For example making an orange colour can be done by using highlights of yellow and shadows of red with another shade of purple tricks you eye to believe the object is orange but is actually a mix of colours, and this also produces depth from these colours. Where as if you want to showcase orange by just using light oranges and dark oranges and grey's makes it less interesting and unattractive because the hue is not changing.

The neutral colours come when you want to change from one colour to another from values. to go from Red to Blue you need the neutral colour which is a dark grey and this will allow the transition into the other colour and will make the colours complementary.

Colour theory part 1

colour is defined as a single wavelength that generates monochromatic light.

Light reflects and changes the way we see colours. for example shining blue light on colours will change how the actual look of the colour. we can use colours effectively to make something interesting and that means you need to mix the right colours to generate shades or highlights without entering the grey scale.

we see colours through our eyes which has rods and cones.

-Rods, convey black, grey and white which is grey scale.

-Cones, have 3 different types which convey the rest of the spectrum of colour which is red green and blue.

there has to be light for us to see colour, without light we just dont get anything but black.

primary colours cant be made by other colours, the two types of primary colours are RGB and CMYK.

-RGB is used for many things such as computers, films and magazines. this is because our eyes see these colours through our cones.

-CMYK is used for print, like newspaper or billboards.

Whats the difference with RGB and CMYK?
RGB and CMYK make additive and subtractive colours, making white and black. RGB primary colours make secondary colours which is Cyan, Magenta, Yellow and key (black) and the same goes for CMYK being primary makes RGB as its secondary.

So why do we use CMYK if we have RGB?
Its mostly to do with print, which is best with CMYK because of the subtractive colours.

Alongside colours comes chromatic values, which are hues, tones and saturation and this is important when it comes to colouring in objects.

-Hue, changes of colours between all the primary, secondary and tertiary colours.

-Tones, adding grey colours into the hue colours and this makes each colour toned down and can mix colours with each other.

-luminosity, brightens or darkens the colours. Darks convey shades and lights convey tints.

colours mix with each other which gives us our primary and secondary colours but our view is not bright primary or secondary colours, we mostly see tertiary colours of greens, blues and grey's and it is pretty much impossible to define the exact colour of something from something that is taken from a camera and this is why we mix colours to produces something that resembles that colour.
