Colour bar

The Colour bar was a system of racial restrictions that reserved skilled work and economic opportunity for white South Africans while keeping black Africans in low-paid, unskilled labor. First imposed in the mining sector in 1904 and extended to the wider economy in 1926, it helped make racial exclusion an instrument of economic growth: white employers benefited from a workforce deliberately denied access to skills, property, and competing livelihoods.

Origins in the Mining Economy

In 1904, the government introduced job reservation for Europeans in the mining economy. Black Africans were excluded from skilled occupations including amalgamator, assayer, banksman, blacksmith, boiler maker, brass finisher, bricklayer, and woodworking machinist. This occupational barrier was an early form of the Colour bar: rather than allowing workers to advance through training and experience, it legally closed off skilled work to them.

The restriction did not remain confined to mining. In 1926, the Colour bar was extended to the entire economy, where it lasted until the 1980s. The expansion turned a sector-specific labor rule into a broad structure of exclusion, limiting black Africans’ ability to enter desirable occupations and compete with white workers.

A State-Made Dual Economy

The restrictions were part of a wider system that prevented black Africans from participating in the European economy. They could not own property or start businesses in the European part of the country, which accounted for 87 percent of the land. The government also restricted education, recognizing that educated Africans could compete with whites rather than supply cheap labor to mines and white-owned agriculture.

That exclusion made South Africa’s divided economy fundamentally different from a pattern in which workers gradually move from traditional livelihoods into modern industry. The state created and maintained the division. Black workers were kept unskilled and barred from high-skill occupations so that white workers faced less competition and could retain higher wages. The impoverished Homelands were not simply a backward sector waiting to be transformed by growth; they helped sustain the white economy by supplying workers whose alternatives were sharply constrained.

Effects and Significance

The Colour bar helped secure an economic order in which white South Africans could invest, hold property, and profit from gold and diamonds, while most black South Africans were excluded from many of the activities that offered economic advancement. The larger system was extractive: white wealth was built in part on the exclusion and low-paid labor of black Africans. The account links that structure to a sharp contrast in living standards between white South Africans, whose incomes approached those in Western Europe, and black South Africans, whose conditions were scarcely better than those elsewhere in sub-Saharan Africa.

The Colour bar therefore did more than allocate jobs by race. Together with restrictions on land, business ownership, and education, it blocked black Africans from using their abilities in skilled work and enterprise, while protecting the position of white workers and employers. Its persistence into the 1980s illustrates how racial exclusion could be embedded in economic institutions and maintained as a condition of growth that benefited only a minority.
