Thus, while income effect of the increase in wage rate causes decrease in labour supply by L2L1 the substitution effect causes increase in labour supply by L2L1. The substitution effect always increases the consumption of the good whose price has fallen; the income effect may increase or decrease it.

But it is stepper more inelastic than that in case of a normal good, in which case the price effect is much strong since its two components reinforce each other or go in the same direction.

Since price effect is the sum total of substitution effect and income effect, we can measure the size of the substitution effect by eliminating income effect.

Simply put, the pure income effect of a price change is the extent to which a change in real income affects the quantity demanded of bread, with relative price held constant. The movement from B to C is an income effect; real income changes, relative prices do not.
