The company, which has 370 stores across Sweden said it had come up with the idea after talking to a number of Swedish anti-racism charities.
"We're looking at whether it's possible to have different coloured plasters but we haven't made a final decision on it yet," Communications Director Eva Fernvall told The Local on Wednesday.
"It won't happen by next week but we hope to have something in place by the end of the year," she added.
Apoteket faced criticism earlier this week by a Swedish blogger who runs the website Vardagsrasismen.nu (which translates as 'Everyday Racism').
Paula Dahlberg told public broadcaster Sveriges Radio on Monday that the pharmacy giant was contributing to racism by only offering shades of beige plasters (also called bandaids in some countries) on its shelves.
But Fernvall insisted that the company's decision to trial darker products was made long before the writer made the comments.
"The fact she said that demonstrates that there are heated discussions about immigrants and refugees right now," she said, adding that the national chemist chain was committed to reducing discrimination.
She admitted that the plaster plan was "unusual" and noted that she had "never heard of anything like this in any other countries".
Debates around immigration have intensified over the last 12 months in Sweden, which currently takes in more asylum seekers per capita than any other EU nation.
The nationalist Sweden Democrat party is the third largest in parliament after winning 12.9 percent of the vote in elections in September 2014 and is continuing to gain public support.
Sweden's government has said it is committed to maintaining the nation's reputation for tolerance and offering help to refugees fleeing violence in the Middle East and Africa. But it has welcomed efforts by the European Commission to encourage other European Union member states to take in a greater share of asylum seekers.
