In a colour television set, the pictures of which one of the following sets of colours is superimposed to generate true colour picture ?

Red, green and blue

Yellow, green and blue

Red, yellow and green

Blue, yellow and red

Let’s look at each option and explain:

- Option 1: Red, green and blue

- This is correct. Colour TVs use the additive colour model, mixing these three primary colours to create all others, including white.

- Option 2: Yellow, green and blue

- This is NOT correct. Yellow is not a primary colour in additive colour mixing.

- Option 3: Red, yellow and green

- This is NOT correct. Yellow replaces blue here, but blue is essential for this process.

- Option 4: Blue, yellow and red

- This is NOT correct. Again, yellow is not an additive primary, and green is missing.

So, in summary:

- The correct answer is Option 1: Red, green and blue

- These three are the additive primaries mixed in TVs to produce a full spectrum of colours.
