Here, connect the other end of the green resistor to a power
rail (output pin of Voltage Regulator).

Here, connect the other end of the blue resistor to a power rail
(output pin of Voltage Regulator).

In the Mood Light Circuit using Tinkercad activity, the RGB LED changes colours

based on how it is powered. Each of the RGB LED’s three colours (Red, Green,
and Blue) can be controlled by adjusting the current and voltage. The 7805

voltage regulator ensures that the RGB LED gets a steady 5V supply, and the
resistors protect the LED from too much current. This creates a colourful mood
lighting effect, where the LED changes to various colours.
