Q1.
Do you know these colour combinations? Colour within the outline and write the name of the new colour. 1. red + blue = p __ __ __ __ e
Answer

red + blue = PURPLE

Fill the six blanks like this: p u r p l e.

Do it yourself: Take a little red paint on your brush and a little blue. Mix them on a saucer, not on the paper. Colour the empty splash outline with the new colour.
Why this works: Red and blue are two of the three primary colours in paint. A primary colour cannot be made by mixing any other colours. When you mix two primary colours you always get a new colour, and the new one is called a secondary colour. Purple is a secondary colour.
Another name: Purple is also called violet when it is bluer, and magenta when it is redder. Violet is the innermost band of the rainbow.
Q2.
2. yellow + blue = g __ __ __ n
Answer

yellow + blue = GREEN

Fill the five blanks like this: g r e e n.

Why this works: Yellow and blue are the other two primary colours in paint. Mixing them gives green — another secondary colour.
Try this: Change how much of each you use. A lot of yellow with a little blue gives a light, fresh leaf green. A lot of blue with a little yellow gives a dark bottle green, like a mango leaf. The same two colours, many different greens.
Q3.
3. red + yellow = o __ __ __ __ e
Answer

red + yellow = ORANGE

Fill the six blanks like this: o r a n g e.

The three secondary colours are now complete: red + blue = purple, yellow + blue = green, red + yellow = orange. Those are the only three you can make from a pair of primaries.
Notice: The colour and the fruit share a name. The colour was named after the fruit, not the other way round.
Q4.
4. red + white = p __ __ k
Answer

red + white = PINK

Fill the four blanks like this: p i n k.

This one is different from the first three. White is not a colour that adds anything of its own — it only makes a colour lighter. Red with a lot of white becomes a pale baby pink. Red with a little white becomes a deep rose pink. A colour made lighter with white is called a tint.
Try it: Put a spot of red on your saucer and add white one drop at a time. Paint a small square after each drop. You will get a row of pinks, from dark to pale.
Q5.
5. red + black = m __ __ __ __ n
Answer

red + black = MAROON

Fill the six blanks like this: m a r o o n.

Black does the opposite of white. Black makes a colour darker. Red with a little black becomes maroon — the deep dark red of a school blazer or a bridal sari. A colour made darker with black is called a shade.
Careful with black: Add black a tiny bit at a time. One extra drop and your beautiful maroon turns muddy, and you cannot take it back out.
Q6.
6. red + yellow + blue = b __ __ __ n
Answer

red + yellow + blue = BROWN

Fill the five blanks like this: b r o w n.

Why all three together give brown: Each colour of paint soaks up part of the light and throws the rest back to your eye. When all three primary colours are mixed, between them they soak up almost everything. Very little light comes back, and what does come back looks brown.
Play with it: More red gives a warm reddish brown, like brick. More blue gives a cool greyish brown, like wet mud. More yellow gives a light brown, like sand.

One thing that may surprise you: Here, mixing all three paints gives brown. But on page 40 Newton’s spinning disc mixes seven lights and gives white. Both are true — mixing paint and mixing light are two different things. Paint takes light away; a lamp adds light. That is why the answers come out opposite.
