Error trying to run HeatmapAnnotation()

[Pio82]

I'm attempting to run a block for HeatmapAnnotation. I'm getting the error:

"Error in col2rgb(colors, alpha = TRUE : invalid RGB specification"
I've copied the code below:

ha_column = HeatmapAnnotation(df = df,
col = list(Diagnosis = c("Uterine endometrial" = "#DDCC77F", "Ovarian endometrioid" = "#0F7554", "Ovarian mucinous" = "#44AA99", "Colorectal mucinous" = "#882255",
"Pancreas mucinous" = "#AA4499",
"Stomach mucinous" = "#D695D0"),

Tumor.Normal = c("N" = "grey", "T" = "black"),

study = c("cgid" = "#332288", "tcga" = "#BD9AF7")))

I'm running rstudio 2022.02.2 Build 485 with R 4.2 on an Apple Mac Pro running macOS Monterey version 12.3.1.

Please advise what the problem might be. Many thanks in advance.

The color code "#DDCC77F" should be either "#DDCC77FF" or "#DDCC77".
