Step 1: Identify the numbers representing the count of each colour: $5, 4, 3, 2, 1$ colours.

Step 2: Recognize this as an arithmetic series with first term $a=5$, common difference $d=-1$, number of terms $n=5$.

Formula for the sum $S_n$ of the first $n$ terms of an arithmetic series:
$S_n = \frac{n}{2} \bigl[2a + (n-1)d\bigr]$

Step 3: Substitute the values:
$S_5 = \frac{5}{2} \bigl[2(5) + (5-1)(-1)\bigr]$
$S_5 = \frac{5}{2} \bigl[10 + 4(-1)\bigr]$
$S_5 = \frac{5}{2} \bigl[10 - 4\bigr]$
$S_5 = \frac{5}{2} (6)$
$S_5 = 5 \times 3$
$S_5 = 15$

Total: $\boxed{15}$ colours
