COLOUR


1.- What is the difference between value and a hue's pure value?
The value mixed black and white and in hue’s pure it don’t mixed black and white.

2.- Write a definition of primary and secondary colours. List each and describe how we obtain them.
Primary colour: are the colours that do not come from a mix of colours but all other colours come from them. For example: magenta, yellow and cyan.
Secondary colours: we obtain these colours by mixing the same amount of two primary colours. For example: green. We obtain green mixing blue and yellow.

3.- What are the warm colours? Why are they called this?
Warm colours are the colours that transmit hot or warm sensation. For example: the orange or yellow.

4.- Give one example of how we can contrast colours in a composition.
For example, if we draw fire in a picture we have to paint the fire with warm colours because the fire transmit hot sensation.

5.- Choose a work of art from the links and analyse the meaning of its colours.


Red: it´s thee colour of the blood but it can transmit happiness.
Green: it´s the colour of the vegetation.
Blue: it´ s the colour of the spirituality.
White: it transmit goodness.


6.- Look for Claude Monet's "Notre Dame Cathedral" and Henri Matisse's "Sorrow of the king" or "The king's sadness"1952. In one of the paintings there is analogy of colours and in the other one, there is contrast. Explain what you find in each one.

The first picture is analogy because the painter used colours harmoniously and the second picture is contrast because the painter used colours with different tones...



GEOMETRIC OPERATIONS

1.- Write a definition of a segment bisector.
Is the perpendicular line that divides a segment into two equal parts.

2.- What is an angle.
Is the part of a plane defined by two straight lines that cross at the same point that is called vertex.

3.- Explain the steps we must follow to divide a segment into five equal parts.
You do a segment A.
You do an other line B and you form an acute angle.
Whiht your compass measure for example 5 cm an you do 5 marks in the segment B
In the segment A you measure 5 cm 5 times
And finally you unit the marks

4.- Look for pictures in the links which include:
acute angle.



right angle.



obtuse angle.



straight angle.






5.- Draw a triangle, a square and a circle. Colour the space in between the lines using different colours.
