If you're not sure, you could read what biographers, historians, and academics who study Dr. King have to say about it.
From the Martin Luther King, Jr. Center:
"'Colorblind'-ness will not eradicate racism. We need a revolution of values and systemic changes. SEE color. LOVE color." — https://twitter.com/TheKingCenter/status/612722539656130560
From https://link.springer.com/chapter/10.1007/978-94-6209-842-8_26:
"Turner (1996) argued that although King supported affirmative action and was more color-aware than color-blind, conservatives have oversimplified and decontextualized his views to support a color-blind agenda. In particular this has been achieved by citing King’s famous line from his “I Have a Dream” speech…At worst, those who use King’s words to promote a color-blind agenda may do so knowingly to maintain a racist social structure, while those who support the notion of color-blindness with the best intentions contribute to concealing a prevailing system of privilege and disadvantage based on skin color. Bonilla-Silva (2003) explained that with the emergence of color-blind racism, “whites have developed powerful explanations—which have ultimately become justifications—for contemporary racial inequality that exculpate them from any responsibility for the status of people of color (p. 2).” Color-blind racism allows white people to maintain their advantages without having to articulate at whose expense."
From https://www.apa.org/pubs/books/The-Myth-of-Racial-Color-Blindness-Intro-Sample.pdf:
“Racial color blindness is a good thing.” This comment is often associated with a vague reference to Martin Luther King’s (1963) “I Have a Dream” speech delivered on the steps of the Lincoln Memorial more than 50 years ago. King eloquently stated, “I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their
skin but by the content of their character” (para. 16). The quote is commonly decontextualized in these lay discussions because the speaker does not take into consideration the context or entirety of the comments. King never intended for people to ignore the realities of racial inequalities. To live in a society in which race does not matter and that people are judged solely on the content of their character is ideal and assumes a level playing field; unfortunately, as King noted in his speech, we did not then—nor do we now, for that
matter—live in an ideal society in terms of race."
Hope this is helpful.
